I've been thinking about doing this for a while because we are always swapping amp recommendations on this site, so here goes...
please share all the amps you've owned or borrowed here and then maybe we'll get discussing?
here's my list:
Acoustic: Model 360 w/folded horn 1x18" cab (loud, deep rumbling bass, amp controls don't do much, recommended for 'feel it' bass tones when you are just asked to follow the chord changes and kick drum)
Alamo: not sure the model anymore, it was a 1x15 combo, not great, but the clean sound was tight and crisp if a bit harsh in the upper mids.... these amps LOOK fender but are more in the supro/harmony/danelectro camp in construction and design, though they are voiced brighter... NOT recommended
Ampeg: 60s Gemini 1 (briefly), 1st year B15 portaflex (borrowed, family heirloom, HIGHLY RECOMMENDED for recording bass), B25B (recommended for dirty bass and clean guitar playing), VT40 (great tone, very "Exile on Mainstreet", best tone controls ever for versatility, maintenance hassle, rare preamp tubes, picky about brand of power tubes, not for the uninitiated), V4B (borrowed, same as VT40 only twice as powerful and in a head w/o verb, recommended for bass with reservations)
Ashdown: MAG300 (borrowed, hybrid design, recommended for bass when you need power but don't want to lug a V4B or SVT, VERY reliable)
Bronson: Melody King (probably made by Magnatone, recommended for blues, some country and harp players, some oddball tubes, not for the uninitiated)
Carvin: X100b (bastard stepchild of a JCM800 and a Boogie, very 80s tones on tap, utterly hideous, cheap carpet covering with no business on Carvin's 80s flagship amp, jack of all trades, master of none)
Ceriatone: 18 watt TMB (borrowed, excellent take on a classic sonically, but I blew her up in NYC and had to return her with 100 bucks for a new OT, maybe that was a fluke though), Dizzy 30 (Matchless HC30 clone, still owned and played regularly, crappy chassis construction, no other issues, survived a year on the road recommended)
Danelectro: DM25 (briefly, fun but a 1 trick pony)
Dr Z: Mazerrati (returned during a no-questions-asked 2 week grace period for a full refund, I DO NOT get the hype, sounded better in the store than with a band), Route 66 (borrowed, AC30 meets JTM45, very British, recommended)
Epiphone: Devon Tremolo (I think that was the model, its been a while and I parted with it after using it for some color on an album... interesting, BRIGHT sound, not a keeper). Valve Jr with mods (borrowed, poor man's ac4, recommended with reservations)
Fender: 1964ish Blackface Princeton reverb (highly recommended), 1956ish wide panel tweed Deluxe (briefly, excellent for rock n roll and dirty country but a little farty pushed into full distortion, all octal tubes, not for the uninitiated), 1963 Blackface Dual Showman (loud and clean, a twin in a head), 1966 Blackface Bandmaster (recommended), Silverface Vibrochamp, Silverface Bassman 50 (recommended for bass), Silverface Pro Reverb (STIFF, not recommended for anything but 80s music and maybe ska), recent Champion 600 (briefly, not for me). Hot Rod Deville circa 1999 (borrowed, sounds a bit lame in person but records okay, cabinets rattle and need heavy duty retooling before hitting record, fully featured for the guy who likes lots of bells and whistles, recommended with reservations)
Gibson: leatherette GA20 (borrowed, cool but delicate so I passed on buying her, not for the uninitiated), GA5 les paul jr, GA20RVT minuteman (briefly, my buddy had scored one to restore at a yardsale and it made me think I wanted one 'til I had it... a good amp for some applications but not recommended for most people), tweed GA14 Titan (excellent deluxe style amp for harder rocking than a 5D3 fender and gainier han a stock 5E3, tight bass at full tilt, same amp as GA6 Lancer with smaller speaker, HIGHLY recommended), 2 tone GA6 (ancestor of the Tweed Lancer and Titan, less gainy, octal tube in V1, sweet sound but not for the uninitiated) GA8?9? Gibsonette (briefly, kinda miss it, very unique single ended amp but finnicky, not recommended for most players)
Harmony: H304A (briefly. champ-like, not well grounded, not for the uninitiated), H420 (very supro-ish, recommended for Zep fans who have the balls to play at 10, not unbelievably loud, but it will piss off the neighbors, stock 60s 15" is usually ready to blow)
Lafayette: LA75 (briefly, intresting voicing, needed a bit more gain, affordable source of lightly used vintage tubes, not recommended for making music though)
Laney: GH50L head (briefly as backup to JCM800, a 2204 with a switchable extra gain stage and a shitty effects loop stifling the tone a bit, low gain input slightly different than a Marshall and not good for Smashing Pumpkins tones, recommended if its 1/2 the price of a 2204 or less), Linebacker Bass model PL100 (recommended for bass, keys and even clean guitar playing)
Magnatone: Aloha branded 1x10 variation of the 109 or 110 circuit with a non-schematic 6SJ7 pentode in V1 (given to me for servicing and then lent to me for a solid year in payment... fun, trashy little combo, RARE as hen's teeth)
Marshall: JCM800 split channel head (briefly, not recommended stock, overly pricey mod platform), Lead 12 model 5005 (solid state practice amp, shockingly toneful for $200 or less, recommended), 1981 JCM800 combo w/vertical inputs model 4104 (versatile, functional, bulletproof, HIGHLY RECOMMENDED as a 2x12, 1x12 or head, sounds different than 100 watt than 2203), JCM900SL-X model 2500 (briefly as backup to JCM800), 1988 1st gen superlead reissue model 1959RI (one of my faves and my longest serving big gig amp and used extensively to record leads), JTM30 2x10 combo (massively unreliable), 1972 metal panel JMP100 superlead model 1959 (in purple levant!), Studio15 model 4001 (briefly, HIGHLY recommended for hard rockers with volume restrictions), 20 watt Lead and Bass model 2061 (borrowed, badassed, HIGHLY recommended), 3rd generation plexi reissue model 1959SLP (borrowed long term as a backup and used extensively to record rhythms), various 4x12 and 4x10 cabinets, JTM45 reissue (rented, head version with EL34 tubes, excellent tone though not terribly authentic, recommended), JCM2000 TSL (provided so frequently as backline for fly dates that I know this piece of shit as well as amps I actually owned, NOT RECOMMENDED)
Mesa: Boogie MkIII C+ (borrowed, not recommended), 90s Triple Rectifier (borrowed, feels and sounds a lot like a poor man's soldano with independent EQ across 3 channels, too many voicing options, even more unuseable gain on the red channel than HotRod50+'s overdrive channel, and not enough definition from the power amp in any of the rectifier modes for this style of high gain beast, when set to sound Marshally this mule will not kick even when turned way up, not recommended unless you are in a Sum41 tribute band)
Peavey: Deuce (borrowed, long story, piece of junk, very heavy and makes a good door stop), Delta blues 1x15 combo (borrowed, like a hotrod deluxe with more balls but no manners, not recommended). 5150 mk1 (borrowed, another Soldano knockoff with a different vibe than the Triple Rec, inferior to the real deal), 5150 mk2 (borrowed, a Soldano kockoff with independent EQ for the channels, not reliable, less toneful than mk1, inferior to an actual Soldano), TNT 115BW (reliable, cheap, sounds passable for bass at rehearsal and small gigs, can be used to amplify keyboards in a pinch)
Pignose: model 7-100 (the original battery powered solid state amp, sounds surprisingly good, originals are collectible)
Polytone: mini-brute II (briefly, well defined but sterile tone, LOUD, infinite headroom, light and portable package, perfect for modern jazz, not recommended for most people)
Roland: Jazz Chorus JC120 (borrowed, nice cleans, best chorus ever, truly stereo combo, too heavy, sounds dated, doesn't take all pedals well, a modern classic but not recommended for most people)
Silvertone: model 1483 head (very Marshally at 10, awful cleans, not unbearably loud, similar to Harmony H420)
Soldano: Hot Rod 50+ (rented, best channel switcher I've ever played, has more gain than one could ever want or need but sounds good with the gain set low too... HIGHLY RECOMMENDED)
Sunn: Solarus (hybrid of tweed/blonde fender bandmaster preamps with trem and a nice reverb driving a Dynaco hifi power amp, "countour" control adds versatility to the 2 band EQ and is more useful than a presence knob, punchy and LOUD as hell! sounds great overdriven if you can handle the SPL, also good for bass, recommended for guys who need power and definition, did I mention it is the loudest dual power tube amp I have ever played?)
Supro: '61 Airline branded Dual Tone model 1624T (cool sound, barely used it, sort of a 2 trick pony... and yes, 1 of those tricks is LZ1 tones if you have the right guitar and a decent fuzz pedal)
SWR: Workingman Bass Amp model 4004 (unreliable, passable bass tone, not recommended)
THD: Flexi 50 (briefly as backup, doesn't sound very Plexi to me, not recommended)
Top Hat: Portly Cadet (borrowed, blown up), 90s Emplexador (borrowed as backup, very authentic 60s thru 80s Marshall tones, recommended)
Trace Elliott: Velocet 1x12 (briefly, voxy in the same sense as a tiny terror, same amp as Gibson Goldtone GA15, mine had some intermittent crackles and bad jacks but never went down, recommended with reservations)
Traynor: Bassmate model YBA-2 (20 watt 6v6 power amp with a bassman type preamp, a bit marshally when turned up, recommended, not loud enough for me back when I owned it, maybe I should get another one)
Univox: model 1050 (a high power tweed twin clone in a head, great semi-dirty sounds at medium stage volume, think modern keith Richards, the similar model 1051 has spring reverb that sounds okay, HIGHLY RECOMMENDED)
Vox: 70s AC30 Solid State (big mistake, good source for vintage celestions as they usually have nice blue painted G12Ms with a vox sticker, not recommended), 1962 AC30B with rear top boost add-on (back in my possession after a couple year sojourn, if you are lucky enough to be able to buy a copper panel JMI made vox, do it), Thomas Organ made Cambridge Reverb Solid State (can be used to get some colorful sgt pepper sounds on records, not recommended), 90s AC15TBX (borrowed to record, tracks were not selected when put against ceriatone 18 watt and Marshall 20 watt, not as good as the 90s AC30TBX, NOT RECOMMENDED), AC30HW2 (currently played all the time, GREAT reissue. obviously RECOMMENDED HIGHLY), AC4HW (not really like an old one if that's what you want, but a very well made small combo with thoughtful features, recommended)
what have you played through?
