It is a preamp (model Jerry Donahue) transistor simulation with HP. Input and output jack, power supply and compartment for 9V battery. It was a setting on the front of the gain (drive), low, medium, sharp and a master volume. The two red switches are used to boost the drive (overdrive / distortion) and switch the speaker simulation. Also connects to a computer sound card. The bypass does not color the sound.

UTILIZATION

The config is simple and effective. The sound is terrible, the warm crunch with the distortion type Marshall. Simulation speaker sounds great, it's vintage, analog 100% No need for manual

SOUNDS

It is perfect for my style of music rather oriented blues, rock. Marshall sounds.

OVERALL OPINION

Sounds very versatile and the vintage +: easy to find great sounds, grain, and simultaneously pregnant -: nothing
