Two knobs, level and effect rponse height, the two are complementary.

do not abuse either one or the other.

input and output jack, power supply or 9V adapter (always better).

UTILIZATION

Trs simple set up, restores the dynamic, is forgotten by the lower course.
the more you attack and was sending it to mdiator trs effective, can be too careful not to overdose.

SOUND QUALITY

I mainly play on my PB 78 us, coupled with the SansAmp (without EXAGRES) I found the sound I was looking for a lease.

OVERALL OPINION

I use it for 3 months and I'm glad trs.

what I like most is adding another effect which makes him a perfect complment.
what I like least, nothing or not much, just do not push it too far not to fill up his sound.

trs good price quality ratio.

I recommend anyone looking for something bigger and better penetrate their dynamics in a mix.
