Building a very simple box is pretty easy IF you have good square/straight cuts on the plywood. Unfortunately a jigsaw isn't good enough. Here in the US, we can get the lumber yard to cut our wood for us at about $1 per cut though. Just make sure you do your measurements well and don't fall into the...

You could do a very bare bones head box for a lot less money, no tolex, no corners, etc. Just paint it black and it will look decent in a utilitarian way. I've seen many racks made like that being used in professional situations.

Adding dual module support to single module amps

I've had a couple of requests for info about the RM20 amp that I modded to accept dual channel modules, so I thought I'd share all the info here on this thread. I don't intend to do any of these mods for folks myself, but feel free to use the info yourself or share it with a tech who can do the mod....

Dual Channel RM-20 head for sale, $400

I'm looking to sell an RM-20 head that I just refurbished. This was the one that was for sale recently here in this forum that had been converted from a combo. After I got it, I made a small repair to the output stage, built a new cabinet with fresh tolex, and added a nice leather handle. I also mod...

I just got back from the amp show and had a chance to run through them all. All I can say is wow! Rob did a great job on these guys. The thing that really struck me is how different they all sounded from each other. These were not subtle shades, but really fundamental differences. I think Rob mentio...

Also, if you have a way to demonstrate a foglifter at the Ampshow, I might be interested in picking one up for my MOD50.

I'll be there at the Amp Show on Saturday. I cant wait to try out some in person!

So I just built that modular bass amp for myself. Do you think any of the new mods might be good for cleanish to crunchy bass?

If you are sensitive to the loading of the cathode follower on the fx send, you can try two things: 1. A treble bypass cap. You wouldn't want a full bypass, so play around with series resistor values along with cap values until you find a set of vales that properly rebalances the highs at your desir...
