Hmm, yeah... That's an interesting read and a couple of thoughts occurred to me - neither to any detriment of Roland, I hasten to add. The first was that, although they make much of the hallowed status of so-called "Tweed" tone, from the narrative and pictures it looks as though they were working more towards replicating the characteristics of a blackface Super Reverb. Maybe that was just in reference to the head-and-4x10-cabinet model, maybe not.
The other thing that came to my mind was regarding what they're saying about the DSP part of it. In solid-state amps there's a means of emulating the interaction in a valve (tube) amp between the speaker and the output transformer. I'm not 100% sure exactly how it works, but it's called current feedback, it's connected with the negative feedback circuit and it has something to do with the damping (or lack of it) of speaker-cone motion. The original Blues Cubes, like some other contemporary SS amps, featured it and it's largely responsible for the warm, full sound that it helps to engender. Perhaps what Roland's engineers have done is to use DSP in that part of the power stage in order to manage the response according to various signal parameters, to a greater extent than might be feasible using analogue technology alone. Whatever. As I said before, if it works and sounds good, it's less important precisely how it's achieved than that it is achieved.
Take counsel from the voice of experience. Don't tell it where you live or it might follow you home. Better still, don't take your wallet with you!
I'm brand new here, but I couldn't help chiming in on this thread. I was up all night reading it last night because I was going to look at a BC60/310 this morning to hopefully buy.
Long story short, I was able to get the BC60/310 for $60. It's in pretty rough shape, but the seller told me that it all works properly (I couldn't test it on the spot). I figure for $60, I'm willing to take the gamble. The ground pin on the plug is broken off (easy fix), but other than that, I'm hoping it's all functioning.
One of the issues is the grille cloth. Some have said that they've bought grille cloth on ebay. Is there a specific listing someone can point me to that will match the original pretty well.
Also, the gold caps are missing on about half the knobs. I wasn't able to get through all 40 pages of the thread, so if anyone has come across a cheaper replacement option for the knobs, let me know.
Here are some pics. They're just the ones from the classified listing because I picked it up on my way to work about 20 minutes ago. I'll take some better ones tonight once I get it home and test it out.
