Numrique with a 12AX7 in Days of buffer before conversion .. For the rest, see the excellent advice donns dj!
Only BMOL, changing the lamp on the MODEL "on line" which necissite the disassembly of the entire rear connection ...

UTILIZATION

Config more pointed than the JMP1 for example, so you have to spend some more time on rglages especially qualisation trs complte and do not over boost gain (55 max)!
In fact, it is necessary to make the sound that was between the two ears and the manual is complete and explicit enough ...

SOUNDS

I think everyone can find the sound! Anyway with my Stratocaster 69 'home-made, there is no problem and I am going to the 535Q, and rotovibe Variphase MXR!

OVERALL OPINION

I use it for several weeks and the only complaint is unable to combine the phasing and the wah-wah in the same preset!! You have to choose .....
I possde other Systmes rack (see my other review) and play a lot of head lamps, but the Rocktron is the compromise for me IDAL all the stuff I have use!
Buy used or new, the report qualitprix is ​​great knowing that voodu together in several racks in a single device!
Repeat this choice .... no problem even if there is definitely better!
