Before I used to be a bunch of transformer or a power strip cord (sssnake). Whatever the solution, I had parasitic sounds in the amp. I even "stupid" separate pedal because I thought there was inconsistency between pedals <=> acoustic amp (Marshall AS100D) or pedals <=> power amp (Hartke Piggyback) with guitars Ovation Legend and Epiphone SheratonII .dropoff window
Now all combinations work quietly: BOSS pedals (CS3 and Super Phaser) Modtone (Vintage Speedbox and delay) and BETA-ALVIN CS100.
Only regret not feeding my Digitech JAMMAN => you need a specific power supply (1300mA)
Choice again: yes yes yes without hesitation .... No more Strip, parasites sounds ....
I am using for nine years.
C'tait my first guitar amp. I pass the lamps since. See anything in sound and dynamics. I bought it on the Internet here based on the videos.
The prampli is not exceptional. It is difficult to keep a clean high volume sound. Crunch sounds are drafts and the distortions very aggressive. As against the DI gave me a good sound for bass. The effects loop includes a speaker simulation (top section) that can not be bypassed, except back into the amp with a jack / RCA cable.
In the end I use as a power amp for my studio monitors (without even a volume knob) on entering the line between cinch (10db).
We must take it as a backup amp in case of failure. It is perfect for a: small and robust. It does not heat.
This amp has all the same few problems. A ground loop doing a background buzz. We can break the ground loop in dvissant Jack sockets (instrument and headphone) in faade. I isolated from mine with fittings attached! Since there is still a "hiss" very low, but nothing to do with the ground loop buzz.
There was also a continued reminder of the problems that I have not had the level of the internal voltage regulator. There is a resistance or diode weld the inside to avoid the. I did a long time ago without any disassemble and I have not had trouble since.
I used this power six months. It provides power 8 pedals 9 volts and 12 volts 2. It parraissait fine. At first everything worked. And then the off button no longer worked properly after 2 months. Shortly after she started to generate me a noise. So I replaced since.
