Help with Cog T-70 repair

[Lunoxx]

Hi all, 

 

I've purchased a COG T-70 through the forum here a few weeks ago but unfortunately it seems to have some headroom issue. If I play as gentle as possible, or turn down the volume of my bass to an absolute minimum, it's fine but as soon as I turn up the volume a little bit or play normally, the T70 starts to distort the signal. Even if everything is turned down and only one of the clean channels is open, the signal distorts quite noticeably. 

 

As to the best of my knowledge COG shut down a while ago (at least temporarily) and I don't know anything about fx circuits and how to fix them, I am searching for someone here in the forum who can either fix/help me fixing my T70, or some suggestions for shops/people to get in contact with. As I've only moved to the UK last year, I'm a bit lost who to talk to for these kind of issues... 

 

Thanks in advance for any help, 

Cheers, 

Chris

Hi Chris 

The T70 (like it's little brother the T65) has a dirty  Octave up feature,to add presence and bite to a band mix (like an Octavia fuzz). It's also well documented that this octave up doesn't really dial out of the tone, when when set to 0. Tom's always marketed this as a synth engine rather than a standard octave pedal,and his speciality is dirt even in his octaves. For clean standard octave the Cog T16/T47 is the one to get. 

Trust me, put a filter in its loop and you'll get a great dynamic synth tone. If you want it looked at to be sure, I've used Owen electronics based In Manchester. Hes very good with Analog pedals (he doesn't do digital) and charges a standard fee (about £11 as I recall) to look at it and correct minor issues, but more if needed. So it'll at least cost that, plus your postage to and back.

Hi, thanks for the response. You're absolutely right, and I'm fully aware of that, but I'm fairly sure something's wrong with my T-70. Easiest example: If I turn everything down in one of the T-65 circuits, and only open the clean channel, I should only get my clean signal (with maybe a tiny bit of noise interference from the octave up feature that I would fully tolarate). However, that signal is quite distorted. Generally, all the "unwanted" noise that I get from my T-70 doesn't sound like the synthy octave up sound but clearly like a headroom issue. A friend of mine is further able to emulate the classic Nerve OC2 sound by putting the filter between 2 and 3 o'clock, however this also results in a distorted signal for me despite identical settings. 

Anyways, thank you very much for recommending Owen electronics. I'll contact them and see what they think about my T-70
