So, simply put, is a bass amp head to:
350 watts (4 ohms) / 500 watts (2ohms)
prampli two circuits: tube (a 12 AX 7) and transistor. These two channels are switchable and mlangeables.

Connectivity faade:
between jack, switch active / passive
pramp tube: pre-gain, post gain
pramp transo: gain
channel switch
swich channels combined

two rglages Tone: bass and treble

equalo paramtrique switch on / off
qualo 7 bands

Balance and Choice of frquence to cut the cross-over (never test. Be careful, this amp does bi-amp: you have to send the x-over to a power amp.

Master
On / off switch

Rear connections: everything you need (and more)
- Two outputs HP jack
- XLR DI with pre and post slecteur qualo
- Effects loop (switchable to pdalier)
- Power amp in
- Between footswitch (6 din plug and not jack)
- "Reset" button that should disable the power supply but ever want / need to press it

UTILIZATION

The setup is really basic: rglage pramp, it mounts the volume, all the corrections 0 and works well.
The argument is quite effective, SETTING THE Tone too. Honntement, the sound is neutral trs correct.
Section transistor is transparent and Fidler to the sound of the bass. The tube section is used to "smear" the sound properly (but loses momentum). Well, it goes up the tube with a Sovtek I intend to switch to the high gain in ground tung, history has any real bitch!
Surprisingly, I found the section transo rounder than the light (but is probably most of my bass).
Well that said, do not look for a typical grain is not ampeg or orange, either. That's only 10 I do not: it does not go in search of cheap full-tube. It is mainly a hybrid lamp but much better than the Hartke.

SOUNDS

I play Rickenbacker 4003, the head sends a cab 12 "Ampeg SVT and it is stunning: round, attack, precision ... everything is l.
I mainly use the transistor section and send the tube to dirty from time to time.
I have no way to buy a full tube (for now), I do not 10 (frustration. ..).

edit: since the change of light pramp (Tung-Sol Gold ECC803/12AX7), I use almost exclusively the lamp section. I now look at a halt for the footswitch to change channels Fawn relevant and practical.

OVERALL OPINION

I have this head than for a short time, I have the opportunity to test other before mine.
It DGIG really feel solid all evidence, feel its weight increases. I do not know o Peavey Arussi not hide the death there must be: it frle rack when the same 20 pounds. Without doubt they had a rich IDE to assemble from pices use of tanks ... That, I think his only concern. That said, there was evidence that at least it's not a head made of cardboard!

I had the opportunity to play an ampeg B2RE: there is no comparison. Currently, T-max are in ultra-ctes as they all sink transistor Ampeg (which is surct. I also made the comparison with the Hartke: photo is not either. Well, I never Hartke t fan but the T-max is a good design quality is in suprieure indniable.

Otherwise, as discussed below, it is actually ultra-powerful. A good way to bury the bastard guitarist! APRS is not a problem ncessairement, sound, even low volume is good trs.

Voil!
