The Temple TRIO 21 is a common size choice for lead guitarists requiring more space for variety.  With enough surface area to go three pedals deep, you've got plenty of room to mount a bypass looper in front while still having access to all your effect parameters. 
 
All TRIO series pedalboards feature one (1) micro module slot and three (3) mini module slots at each end.
 
Comes with black nylon Temple TRIO 21 soft case.
