I could ask if the MusicMan 115 RH bass cabinet's "Electrovoice Speaker Upgrade" (offered on the pricelist as an up-charge) upgraded to an EVM 15B or an EVM 15L, and how in your opinion did change the tonal characteristics, depth extension, and output of that box? Some of us still have a "healthy" appreciation for non-micro classic gear, and someone here knows the answer to this question, but doesn't participate much for some reason.
