Line 6 DL4 for your delay
Line 6 MM4 for your tremolo..and chorus, and flange and rotovibe and univibe, and phaser...on and on and on. You get 3 presets for different delays and 4 presets for different modulation effects with these two pedals.
For tube distortion I've got to recommend the Tonebone pedals. 12AX7 driven, everything from smooth and deep to whacked out marshall on crack type tone...depending on which model you pick.
I own all of the above pedals, the tonebone being the classic version. Let me tell you, those line 6 modeling pedals are fantastic stuff. Tons of features, great sound, can run expressions pedals and control any parameter or combination of parameters in real time, plus your tap tempo feature. Now that I think about it, I'm not sure which pedal has the trem model. It may be the DL 4 and not the MM4. If it is the MM4 then you won't have the tap tempo available for that model, but you could change the pulse timing via
expression pedal no matter what. Oh and they're also stereo pedals...really cool stuff there.
I picked up a tonebone classic because I wanted to emulate that old plexi tone, really chewy and thick. This pedal is as close as I've heard, and it's a grand less than a real plexi.
My chain looks like this:
Guitar>Ernie Ball Volume>Tonebone Classic>A/B/Y switch
A side out to Rivera TBR1SL
B side out to Mesa Nomad 45
A side FX loop: MM4 Right>DL4 Right
B side FX loop: MM4 Left>DL4 Left>Boss RC20 loop station
Have Ernie ball
expression pedals for the MM and DL pedals.
Must, absolutely must plug the line 6 modelers in to power them, they eat batteries like crazy...and big ones too, C batteries. You'll be out major cash in no time if you put that off. Dump the cash up front on a Voodoo lab pedal power 2, you can run two line 6 pedals off of it...those things are worth their weight in gold.
Price wise you're going to have to find them on **** used to hit your mark of $180 per pedal. New tonebones are $230 and the line 6 stuff is more than that. The only other drawback other than price is the fact that the line 6 stuff takes up a fair bit of real estate on a pedal board. I am almost finished with my new board and it is a monster.
