Hmm. I one of those who subscribes to the theory that, outside of the player themselves, the biggest contributors to tone are the transducers in the signal chain - the pickups and speakers. The speaker is also reliant on being in an appropriate cabinet. I can’t help but think that a sub £100 amp won’t do a well built/equipped guitar the justice it deserves. That’s not to say that you can’t get a decent sound from a small amp, it might be the very sound you’re after, but I don’t think it’s in the same league as something more conventionally sized and with more power. Just my 2 cent’s worth, others may think differently. Go and try some ‘better’ amps when and if you can.
