Being new here, I've done a lot of reading and noticed the availability of the parts you mentioned. I just noticed no mention of logos-the one (two) thing I need. O.K, I starting to catch the Sunn light and will keep my eyes open for a matching amp. After finding this site, I dug out my cabs from the garage (I know-please don't kill me), pulled the grills off and scrubbed them down, scrubbed the tolex, fired them up and viola-I see what people are talking about as far as these cabs. Warm sounding with a different midrange projection than the SVT cab. A different kind of bite from my rick. I'm loving both sounds-gives me more variety of tone and plan on trying out all three cabs together. I think they will compliment each other. All I need is people to help me carry them to gigs. I envy those guitar players that can blow you out of the room with a single 12". Back to the logos-I don't know which one's I need at this point and hopefully someone can tell me once I put up some pics. Did I read that there should be a back plate with a serial number?-not that I expect to purchase them, I just like to know what's missing. One more thing on the logos- it seems mine were originally mounted at the bottom right corner of the grill as I see 4 tiny screw holes there and nowhere else on the grills. Is this where they were mounted? It just seems odd to mount them at the bottom. No, I don't have the grills upside down as the snaps line up only one way. Finally, thanks for the response-I was wondering about the cat getting all the tongues out there.
