Re: Robben Ford & His Dumble Overdrive Special
Here is a video of him playing the amp live back in 1988. I believe that is his dumbleator sitting on top of it. I noticed the amp did sounded a little darker here with the dumbleator. It still sounds amazing!! I wonder if the ageing of the components over time also changed the sound of the amp. ht...

Re: Next up, grill cover
Mellotone DF6000 - So this stuff is close to the Fender original? I need to re-cover my old Tremolux 64' which is in poor shape. Some of the grill stuff is plastic and degrades, is this DF6000 an actual material weave? Ange Hi, yes thats correct DF6000. Its what all the big resellers like Mojotone ...

Re: Transformer transplant
Grounding speaker jacks at or near the jack is always the best option. If you are using jacks that do not self ground just place a terminal solder lug at the floor of the chassis near the speaker jacks.

Re: Next up, grill cover
When I have tried stapling piping, my stapler wants to push the piping out of place. In other words, I can't shoot staples close enough to the piping to avoid pushing it out of place as I staple. Advice? Hi, I use a Dewalt powered stapler and I let the rounder part of the piping roll over the front...

Re: Next up, grill cover
Thanks Martin, Bill and Guy for your responses. They were helpful. I just finished the grill cover and piping. I'm very happy with the look of my grill cover. However, I'm a little disappointed in my piping job. I didn't find any good tutorials on installing that. Hi, the secret to piping is to cut...

Re: SSS CF Driver Compression Questions
I believe the Mhartman version of the SSS has the mixer tube that mixes the clean and reverb signals like the JM Signature clone. I wonder if changing this can get you what you want. The #005 SSS does not use that method of mixing the clean with the reverb and it has lots of gain on tap. You can lis...

Re: SSS CF Driver Compression Questions
A part of the compression is coming from the LNFB loops. Especially when you drive the first volume pot a little more. Not all SSS are the same as are the LNFB loops. Which one do you have? Erwin My build is adapted slightly from MHarman's Layout which I believe is based on #004. So I see that I di...

Re: Next up, grill cover
I just completed the tolex job on my first speaker cab. Now I just need to do the speaker grill. I'd like to make it look like the attached image. Does anyone know the name of this type of grill material and where to buy it. Also, what is the white part called? Binding? Hi, here is the grill cloth ...

Re: SSS CF Driver Compression Questions
I like how it sounds when the Phase Inverter and CF plates are around 240v. This was with SSS #005. That's a good point about the Master Volume. I never experimented with that. I will test that out when I have another one finished later in the year. Happy Easter and Happy Holidays! Guy Happy Easter...

Re: SSS CF Driver Compression Questions
I have found that adjusting the voltages on the Phase Inverter and the CF plates can effect the level of compression. Try lowering them and see if it gets you what you want. Cheers G OK, thanks! I was wondering about something like that. What sorts of voltages did you end up settling on? Did you al...

Re: Two Rock Classic Reverb Signature Schematic (Current Version)
And I've found Studio Signature's detailed guts which is supposed to be 35 watt version of the amp(minus rock jazz switch, tonestack bypass and fet). Don't know if it is true or not but this one can probably help too. The mixing tube wiring on this Studio signature looks a little different than the...

Re: New Project
No problem, it's all good input! Sounds good, too. Interesting you had success with a 6L6, what with its need for more drive voltage than an EL84 or 6V6. Thanks Martin, its my friend Kyle playing the amp. I would like to turn back the clock to being that young again LOL. I was thinking the same thi...

Re: New Project
Excellent! I had forgotten all about that. I have the schematic Colossal drew up, which has some good ideas. Matt drives an EL84 directly, where I'm planning on a 6V6. I want to ditch the preamp out/power amp in, and take a line out from the output transformer. That will be driving either a resisti...
