Critic Reviews

Hiwatt T20 Amp

guitarinteractivemagazine.com

The Hiwatt T20 Combo offers an affordable entry into the world of valve amps, sporting a cool design and a reliable build. Made in China, it doesn't feature the UK craftsmanship of pricier Hiwatts, but it maintains the brand's sturdy reputation. While the amp includes useful EQ controls and an effects loop, sound quality is where it falls short. Reviewers found the tone somewhat flat and lifeless, with the clean channel lacking depth and the dirty channel offering a fuzzy rather than gain-rich experience. Despite this, the T20's price point makes it a solid choice for budget-conscious players seeking classic Hiwatt aesthetics.

Hiwatt T20 Review : Hiwatt It All - Audiofanzine

audiofanzine.com

The Hiwatt T20 Combo delivers a classic British clean sound in a compact package, ideal for home use and small gigs. Its clean channel shines with clarity and works well with effects, maintaining the legendary Hiwatt tone. However, the lead channel is less versatile, offering a distinctly muddy and grainy sound that may not appeal to all players. This channel suits punk and classic rock but struggles with modern styles and humbucker pickups. Despite lacking an FX loop, the amp's clean channel handles effects chains well. Overall, for its price, the T20 is a solid choice for those seeking a distinctive clean tone but may not satisfy those looking for more versatile distortion.

Very happy

One of my favourite amps in the world. Takes pedals like a champ, Very clean headroom. Don’t be fooled by 20 watts, this thing is very loud and can hold up to a drummer even on the 10 watt setting. No matter what pedals or amp setting i use it’s very usable, Only one thing to say is that the overdrive channel sucks and would’ve been better if it was a bright channel or a presence boost. Ether way this is a very good amplifier if you’re looking for a pedal platform or something that can stay clean.

Preferred Settings + Usage:

The settings actually differ for what i’m using it for and what room i’m in. But most of the time i like to have it clear and warm with a little bit of sparkle in the High end.

So it would be like: Bass. 70% Middle. 40-60% Treble. 30-60%

Roles:
