Small Footprint Preamp Needed for MAC MC30 Amp

[zozoe]

Greetings... Not quite certain where to post this, here I sit, trying to figure out the best type of box, pedal, or whatever, to put in front of my Mac 30w tube amp to have a hopefully unique & usable 'rig'.... The one that my attention returns to is the Effectrode SR-71 Blackbird unit,,, Since the Mac has no volume or input attenuator, one consideration was to use only the 2 output channels of the SR71, (ignoring the 'Bypass', not knowing how the amp would react to an 'open' or no load), keeping one ch. squeaky clean, & the other for edge of OD, & reassigning the Bypass to switch the Classic/Creamy options..... Footprint is important, & I'm trying to work around the FYD or Sarno SMS route, though both phenomenal options.... I want channel switching between clean & edge, & reverb not necessary....
Thoughts, opinions?
Many thanks~ॐ
