First I'm a big fan of compression and usually have one on all the time (unless I'm looking for a tone that is compression free) in front of every thing else, which for years has been guitar, compressor, amp ( compressor has been a Boss pro CL 50 half rack unit for years until I recently went with Origin Effects stuff). I have no time based or modulation pedals, all that comes from rack pieces in the loop of after the center channel amp in a wet/dry/wet set up.In the past few years I've start in on collecting pedals again. I've had a V-twin pedal almost since the first came out and can say unequivocally that's only pedal that I have that doesn't work for me in front of a Boogie, It get's used mostly with my Fender amps. All the Boggie amps I own (see below) work well with a KOT from Analogman and I'll all so stick a Beano Boost in front of my TA15, on all the time, into the Top Boost channel. Both of the Hermida Zen Drives really add a bit of Smooth to the TA 15, I like them especially on the Tweed Mode. Set Up A good Fender type clean tone on Any of them, I like setting up a Clean edge of break up on the Recto mod Channel on the Triaxis, and the Ethos Overdrive can do it's thing like a charm, Love me some Carlton/Ford kinda tones. I have Set up a great pushed quasi clean blues tone by pushing a BK Buttler Tube driver with the KOT, into the Blended Channels in parallel on the V-Twin RM 20/20 combo that cleans up by backing off the Guitar volume and varying pick attack, And Lastly I love the tones from my both Tiki Drive and Nu-Valve (Hermida) into The Recto mod channel of the Triaxis, the hi gain channel of my V-Twin Rack unit or the Hi Gain channel 1 on the TA. I Can get some real Aggressive Marshall kind of sounds with these two, bite, snap and articulate. All of the wide variety of tones Boogie amps can deliver can be upped a notch with just a littlr more gain hitting the front end.
