Umble is a FET-based emulation of a certain very expensive amplifier...

Nice........someday I'll be able to catch up on building all of these!

(Any hints on what the last emulator will be?)

The Umble is our last entry in the FET-based amp-emulator series at runoffgroove.com

It's been a lot of fun and we've learned quite a bit, but it's time for us to take a short vacation and move on. Our goal was to help others learn the conversion process, while producing several examples of the more popular amps. Of course, we'll be happy to help others with their FET-based emulations.

Thank you to everyone for their feedback and enthusiasm! None of our emulators would exist without this forum and its members.

Hey Mr. B,
It's Us Wee Guy's here that owe our Gratitude to GUY'S Like You'all for letting us enjoy,

My Thank's to all you GUY'S,

How hard would it be to convert these things for use as preamps? I can see tossing a bunch of them into a rackmount unit then pairing it up with a good tube poweramp. Sort of like the Duncan Convertible.

The tone stack is more of a cross between a Vox and a Fender. Vox layout with Fender values. HIGHLY interactive, in the sense that it seems one knob doesn't do anything (like the mid knob) until you get the bass or treble knob in a certain range. Or if you dial in a nice sound but think "hm, it could use a touch more bass" and turn the bass knob up a bit - no change, until you turn down the treble and mid knobs. Weird stuff like that. This interactiveness makes dialling in a lot of different sounds possible, but it's not a quick process. I strongly suggest writing down or taking notes on the tone stack combinations that work for you!

i hope this doesn't mean you 'll stop doing emulations in the future...

thanks a lot for all of your pedals they are great...

I've never heard a Dumble being put through the paces on its own, but even if it doesn't sound exactly like one, it is one cool-sounding pedal. Lots of tones in there for sure.

As for pursuing other projects (and a vacation, which you guys deserve) I'm excited to see what you come up with. Now we have a cornucopia of amp sounds to pursue, and I can't really think of another classic amp I'd like to hear except for maybe a Hiwatt 'Live at Leeds' pedal.

Anyway, rock on guys and despite the claims that you are putting out too many projects to keep up with, keep 'em coming!

Disregard the above quote. I just read the "Runoffgroove request" thread and this was dealt with down the page.

WoW!

Got to run at the el-shop when the morning comes. Very good soundclips :shock:

One beginner-question:

Are the bass, treble and master pots logarithmick and the middle linear ?

Thank You,
mat

Mr B, Gary, Comgratulation's, you win the Ceegar on this 1, I been on Stage teching for Mr. E.J. and i'm gonna tell ya, if ya had the delay and reverb set like Eric does it, you woulda nailed his tone through that Randal amp, I love it, that's incredible, I just now got around to listening to the MP3 and i was very suprised at what I heard, you know what they say," Save the Best for Last ",

Gary · July 13, 2004, 08:34:07 AM

Thanks, JD. EJ is one bad cat! I wish I had half his talent.

Michael Weidenauer · July 13, 2004, 01:23:25 PM

Sounds great, I think I have to build some of your pedals, but I've got a few questions:

Are these pedals inteded for:
use in front of a clean guitar amp,
beeing plugged into a power amp
or directly into a mixing-desk :?:

Anybody tried using BF244s or BF245s instead of J201s ?
If yes what worked best: gain category A,B or C?

Thanks for your work ! :wink:

Michael
