"I just thought I should mention that the 'Custom 35' amp has far exceeded my expectations. I knew I was expecting to get an amp that was better than anything I had ever played. I hadn't quite expected it to be this damn good. I did a small jam with the other guitarist in my band the other day, and he was well impressed. I don't ever need to worry about having to compete with the drummer and bass guitarist ever again...."

 “I am extremely happy with everything about this Amplifier.  It is everything I could ever dream of for my acoustic guitars, and I know perfectly well it will be fine for my solid body Les Paul, for that burgundy velvet tone we were going for.”

recycle later on.  five watt 12BH7 valve amp12BH7 valve guitar amp


Steampunk Guitar Amp 25R
The "Ampenstein" amp head is an all pentode amp, made up of two pentode gain stages (EF86 and 6J7)  with a Baxandall tone stack (bass and treble) and a triode strapped 6J7 
phase splitter driving a pair of 6L6GT power valves for 25 watts.  GZ34 valve rectifier power supply.  
The amp is finished with the steampunk aesthetic, with a brass plate etched using electrolysis and mild acid.  The pattern behind each control knob is taken from the 2010 season of crop circles in the UK.  If Doctor Frankenstein played guitar, he would have used this amp.

"Ampenstein can achieve controlled distortion from ANY and ALL of the valves from preamp to phase inverter to power section!   I only had a half hour to mess with it last night, but there are at least 3 or 4 tonal flavours available seperately - one from from each valve, and these can be combined for even more flavour."
