There's a Mergili innovations Big Boy Elroy popped up for sale locally. It's a Harp amp by all accounts, running 4 x 12ax7, 2 X 6v6 and a 5ar4.
What I want to know is, are they any good for guitar?
What's the output power from the pair of neo Jensen's?
They're asking £1100 after a price drop ...old reverb listings have them sub £800 but probably still stateside.
It looks like a cross between a Gretsch executive and a Fender excelsior.. cheers!!!!

Cowmoo , as you know I'm a big fan of the harp but .....
In all honesty I've never heard of these amps . Most harp player look for in an amp is that raw bluesy sound . Seems John Mergili builds " one of a kind " amps from the ground up , therefore , probably making this amp specifically for the harp player . In fact in one of his " testimonials " on his web site , a customer speaks highly his " harp " amp . He's in Spokane , Washington , USA . I'm sure you've looked but heres the link

@thunder58 yes, I had a look but there seems to be very little on the net about guitar amps....he makes some incredible reverb/tremolo units which work great before an amp by the looks of it..
I'd like to try a guitar through it but hate viewing items if I'm not intent on purchasing. I'll keep a watch on this Elroy amp and see if I can find out any more.

Seems he rebuilds and repairs amps as well as building new ones. He shows that he refurbs old Masco PA amps (for that octal goodness). Guy does some interesting cabinetry.
