Vintage (in order of bassman contrast):
Polytone brute or minibrute, more than 30w but solid state so whatever
Vox solid state amps, UK or US... "like a blizzard of nails!"
Vox UL30
Any ampeg guitar combo with 7591 output tubes, the reverborocket is the most fendery, but still very different
Gibson minuteman or falcon, 60s front mounted control panel, not tweed/crestline
Standel amps, tube or solid state
Magnatone, not new ones
Gibson Leatherette and 2tone amps, 40s/50s, avoid field coil speaker equipped models, have a tech on call if you can't read a schematic and solder. Reliable once serviced. The ga20 leather and ga77 2tones are personal favorites.
Harmony Amps with el84/6bq5 output tubes
Oahu lap steel combos with Hawaiian motif grille cloth... champ and deluxe like but different, good ones should have all octal tubes and tiny transformers
Any danelectro, particularly the dm25
Vox ac10 or ac15, vintage JMI combos with ef86 preamps, not the reissues
Any supro, national, airline or gretsch with 6973 power tubes and some supros with 6v6es, grid leak bias inputs will be the biggest contrast
Tweed and crestline Gibsons, particularly the lesPaul, ranger, lancer and titan... more like nastier 5e3s, pentode or grid leak biased inputs, paraphase inverters, different flavor, low headroom grind monsters
Watkins Dominator 18 watt
Traynor YGM4 studio mate
Marshall 18 watt, 20 watt Treble n Bass, Popular or studio15
Selmer zodiac 30
Vox ac10srt head
80s Hiwatt custom 20, audio brothers era, not current
Vox v15
Trace elliott velocette 1x12
Handwired ac15s and ac4s
Tweed deluxe, princeton, Harvard, tremolux or champ
Mesa 22 caliber
I'm sure I missed a pile
Stay away from harmony 605, kay amps and the dano amp-in-case, electrocution hazard!
