That little blue amp is one of my coolest acquisitions. It's a handmade amp by a dutch ampbuilder. its the preamp of a vox ac15 and the endstage of a marshall studio 15. Its really LOUD and POWERFULL for 15 watts, haha. its like a mini-plexi, but with more gain. its got the best clean's I've heard for such a small amp,and the overdrive is just delicious. This guy will make me another amp, which will be KILLER. its a real fender twin, dumble ODS (ceriatone OTS) and marshall silver jubilee (with tweaks) all in 1 head (but with 3 different, independant output stages, but with 1 PT and 1 OT). i can run a guitar through all 3 amps at the same time, but also seperate. The OTS and the silver jubilee will get an extra gainstage, to give me just a bit more power.
