Thanks for the kind words and insight, folks!
Per the need for more reverb, I think it was my recording device (a voice recording ap on my iPhone) or mic placement that was dampening it. The reverb on the SMS was around 11:00 and sounded very wet in the room..
Thanks for the comments on obel/buffer/tone. I truly didn't know how the obel/buffer would impact things tonally. I now think I have a better feel after your comments. Another thing that comes to mind are my pots. They are factory (likely cheap Asian parts)...I imagine I should upgrade them? If so, what value pots go where? Or should I leave things as they are?
Even with this invaluable resource of the forum, one goes in sort of alone and blind in the quest.
It took me forever to work out the gain structures between the 2 volume controls on the SMS, the Mc40's volume and the guitar volume pot. What worked for me was 10:00 on the front of the SMS, 95% on the back of the SMS, 95% on the Mc40, and the guitar volume way down....like maybe 30%.
The tone pot on the guitar was a wrestling match as well, as my initial inclination was to dime it....something wholly unworkable with the Super 2.
But the constant tweaking of combination of gain structure, tone structure, action, and pick up height allowed me to approach the desired slight speaker breakup I'm getting on occasion (along with some sound advice on e-120 vs. k-120 from a certain Mr. Sarno).
I'm still trying to coax more sparkle and sweetness from the rig. At times I suspect this will always be the case.
Then there are the weird invisible variables. Like the night before it was as perfect as it has ever been, but the next day you power up, and even with the exact settings it sounds like shit. At first I thought it was my ears, or something moved in the room, or the humidity or something. But what I learned is the SMS sounds progressively better the longer it is on, and it sounds much better after a 5 minute warm up. It also finally sunk in to my thick skull that it takes me a good half hour of playing before my touch with the pick gets decent.
Anyway, thanks for enduring my longwindedness. Thanks for the collective brain power too!
