I have a Crema Wheat with the Scumback M75 25W speaker installed. This amp + a SC tele is a match made in heaven, however, I am thinking that my other guitars (especially humbucker pups) might appreciate a speaker swap that opens up the high and low end a bit more. Does anyone have experience with other speakers that they really liked in this amp? I've read here that the Celestion G12 H30 70th Anniversary is one possibility, and am curious to learn whether anyone has tried (and liked) any others. I am primarily looking to enhance the ability to get a less mid-centric rhythm tone with the guitar's volume rolled back, without sacrificing the fat, bold lead tones the amp already delivers with the Scumback speaker in it. Maybe I should try the Scumback H75 with the LD option? Also, if I could find an Alnico speaker that would fit without mecahnical interference issues, can anyone comment on what tonal differences I should expect from such a speaker in this amp? I appreciate in advance any thoughts from experienced users.
