A transistor amplifier completely, from 400 watts into 4 ohms and 290 watts into 8 ohms
simple connection of utilistation
not very simple with adjustable parametric equalizer
but good potato

UTILIZATION

The config is very simple, the sound is very transistor,
little warm and round, it is difficult to get a sound that fits you if you like roundness and warmth, dynamic c'eest very little to be ca blues rhythm and blues and even the rock,

SOUNDS

For me it's not my amp, I seek an ampeg head because I play blues and rock, however my active jazz bass us a very good rendering, exept in the roundness and warmth,,,
I like this amp because it is very effective, but poorly suited to my game,
it's a good amp for a modern sound and music that sends,
So much for my part I'm going to separate,

OVERALL OPINION

I use it for several months, suiuvant the studio and I repeat the baffle is available I find that I will sound good in any cabinet ampeg or SWR on it sounds better in my case,
I try the 3500 ha before and I prefer the 4000 ha of INPED for some reason, it works 4 or 8 ohms, it suits me because I have a Hartke 410 XL speaker config etampeg SVT 410 HE It gives vitality and a little more roundness,,,
value for money is exellent although sonb does not suit me,,,
I would do not buy this head, I would opt for either a hybrid or head lamp, in all this is a very good amp, it's on if you like the sound, especially as le'equaliseur setting provides a good range of sound,,
