Transistor amplifier for acoustic guitar electro-60W.
A guitar input jack through with equalization (low, medium parametric acute) and a gain.
An input jack or XLR mic with bass / treble / gain.
IN general, volume and reverb type spring.

At HP, a celestion and a small tweeter (the most beautiful effect in acoustics).
Possibility to bypass the tweeter via a button on the back).

An effects loop (send / return).

UTILIZATION

The configuration could not be simpler. The setting is really suitable for an electro-acoustic (especially the equation. Parametric).
The second way is neutral / colorless allowing me to plug a pedal type Line6 Pod X3 Live and get all the sounds I want with my Les Paul!

SOUNDS

I can connect both my and my AE via electric pedal so it's super versatile ... super!
The HP celestion delivers a nice feature with a very broad spectrum.

OVERALL OPINION

I haveused it for over ten years and I would  not part with it, it is lightweight and compact, ideal to use at home, great for the studio and I have already used it on stage to condition be taken up front.
It's a great ratio Q / P which has an electro-ac, an electric and pedal.
Before having the pedals I use with my TUBEMAN and it is also divine sound lamp nickel!
