Who else uses a BOSS GT-10 ?

Me. I use it for cleanish stuff only. The thing I like most about it though is that it has a digital out. Some of the fx are very nice IMO.
HUGE leap from the GT5 I bought 10 years ago.
 
I had to set the Send to 100 and Return to 180 to make sure the Bugera wasn't attenuating the signal too much before it came back into the GT-10. Was it similar with the 5150, Markus? I use the Output on the GT-10 as a master volume anyway and that seems to work fine.

I also set the assigns on the volume pedals so that when it is fully heel-down and 'silent', the tuner comes on - useful for tuning up between songs or quiet sections. However, it's not truly 'silent' for me, and I think that's the fault of the amp being not entirely wired in serial (although how that is possible, I have no idea).

Also, another 'trick' I just remembered: I try not to change patches during a song as the patch change time is just too slow and noticeable. So I usually have Ctl-1 and Ctl-2 set to switch several things at once (eg. I have one patch where Ctl-2 adds EQ, reverb, chorus, and delay, to change a rhythm sound into a lead sound), and can also use the Channel A/B switching to go through very different configurations with no latency.
 
I didn't remember exactly how I set the levels,
but I remember like it was yesterday...that it was a lot of hassle :D

I don't get it, why a lot of Amp Manufactures set their Master Volume before the FX-Loop.

I use the Boss' Master Volume too, but I don't really like it.
Playing directly with a cable into the 5150 (or any other amp) is something completely different (in a good way). :mad:

I also changed from Preset based Patches to switching FX on/off.
So my delay can swell out when switching to clean f.e..

Cheers, Markus.
 
GT8 + 6505 with 4 CM here.

My FX loop send/return are both at 100 but the master volume (patch) must be at 126.

And here is how I set the knob in the back of the unit. Take note that I only use the GT8 for FX, I don't use the amp sims that are built in.

GT10 + ENGL Invader with 4CM here.
I use the GT10 for effects, cleans and leads, and the ENGL ch3 for rhythm. Did not have much problems with the levels, in fact I bought the GT10 because with it I could finally balance out the levels, instead of having to live with signal loss like on my old GT5 (which collects dust now).
