Transistor.
Equalizer (low, low mid, high mid, high)
exit from loop effects.
"Mid Snotch" kind of button attnuation trs nice but not really a compressor, just a bass sound deeper.

UTILIZATION

Use trs simple.
One branch is played.
The sound is not too bad (japan fender precision bass) but high volume, tendency to saturate.
Use bagpipes / folklore, never to return.
No manual.

SOUNDS

Button switch that gives a nod that I like her but apparently scne, it is too dull buzz. So, sniff sniff

OVERALL OPINION

I've had a decade c'tait one occasion.
It's a versatile bass amp if you do not grow too much into a corner.
I tried the amp in its class (150/200) with compressor and all the trimmings that have better sound but more typ So, for home or for concerts undemanding, this amp is a good choice.
Report quality fair price, but nowadays it is much better print some.
