Members derek_32999 Posted January 5, 2007 Members Share Posted January 5, 2007 At least they vented the tubes so they dont overheat.... Link to comment Share on other sites More sharing options...
Members harshoul Posted January 5, 2007 Members Share Posted January 5, 2007 i love this led behind the tube thing, reminds me of how dumb we gear heads are. Link to comment Share on other sites More sharing options...
Members mfergel Posted January 5, 2007 Members Share Posted January 5, 2007 You wouldn't believe how much gear does that with the LED's. Vox Tonelab's, Digitech 2112 and 2120 (maybe even the 2101), Behringer stuff, etc. Yeah, it's bit stupid but the best way of determining if the tube has an impact on the circuit is to change out the tube. I've done this with the Tonelab and it makes a big difference. Link to comment Share on other sites More sharing options...

Moderators AMZ-FX Posted January 5, 2007 Moderators Share Posted January 5, 2007 The Cooltron pedals DO depend on the tube for their sound but the low voltage/current circuitry will not make the tubes light up... patented circuitry, BTW... regards, Jack Link to comment Share on other sites More sharing options...
Members Eye_Of_The_Liger Posted January 5, 2007 Members Share Posted January 5, 2007 I think this article in GP magazine will help clear things up: http://www.guitarplayer.com/story.asp?sectioncode=6&storycode=9656 Link to comment Share on other sites More sharing options...
Members SerpentyneXIII Posted January 5, 2007 Members Share Posted January 5, 2007 Originally posted by comfortablynumb The tones are really great. Sounds like a cranked tube amp.. lots of harmonics. Very full sounding. I wouldn't mind having a mid knob, but I really don't miss it. Here's a clip from one of our demos we did a while back. http://www.soundclick.com/bands/songInfo.cfm?bandID=605480&songID=4848687 "Uses a duet of premium, mil-spec, subminiature, USA-made Phillips-Sylvania Link to comment Share on other sites More sharing options...

Members 2manband Posted January 5, 2007 Members Share Posted January 5, 2007 As I understand it, the low voltage toob operates with next to no headroom (due to there being next to no plate voltage) so it clips the signal. This is exactly what you want a distortion pedal to do, no? I think it's a good design for a distortion pedal. For a rackmount mic preamp tho - Link to comment Share on other sites More sharing options...
Members jove Posted January 5, 2007 Members Share Posted January 5, 2007 All the Cooltron pedals I've played thru sounded great.I demo'd all except for the Over the Top Boost.The tube is being used as an integral part of the circuit (from the Vox website): Want to know how it all works? Normally, tubes are used at high voltages and this restricts their use in battery-powered devices such as guitar effects pedals. Historically, attempts have been made to use tubes at low voltages in what has been dubbed Link to comment Share on other sites More sharing options...

Members therhodeo Posted January 5, 2007 Members Share Posted January 5, 2007 I'm really wanting the Vibravox when it comes out. I like the looks of it. Link to comment Share on other sites More sharing options...
Members GRINGO_LOCO Posted January 5, 2007 Members Share Posted January 5, 2007 Originally posted by AMZ-FX No, the tubes in the Cooltron are used as common cathode gain stages just like in tube amp, not as buffers. There is a special servo circuit that makes the bias stable at low voltages. The heater is also run at low voltage and current for longer battery life... too low to make it glow. Best regards, Jack Yeah, I couldn't remember if the Voxes used the "tube buffer" trick or not. I know that the Radials use it to help get around some patent issues (BK Butler). Thanks for the info, Jack. GRINGO Link to comment Share on other sites More sharing options...
Members GRINGO_LOCO Posted January 5, 2007 Members Share Posted January 5, 2007 Originally posted by RUExp? They use some kind of mini tube. I think they're like the ones in the z.vex nano head. IIRC, a couple of 6021 sub-mini tubes. Link to comment Share on other sites More sharing options...

Better than a jury of Amp forumites. "Has the jury come to a unanimous verdict?" "Yes we have your honour." "Then what say you?" "Brewtal gain M'lord!"
