I have this little battery powered guitar practice amp, made by
Pignose. It sounds amazing - a bit like a Marshall 100 valve amp in
fact, and I could never work out why. These things are used by plenty
of big names on-stage, as well as plenty more who won't own up to it.

Anyway, today I had to take the cover off to fix something and I found
the reason for the meaty sound. It is a mini solid state valve amp

Who'd a thought it?

Yes, it's the colouration the transformers give to the sound !

Have you seriously only just realised that ?
