RH750 Fixed and great TC Electronic support

[Shylock]

I thought I would share the solution to my TC Electronic RH 750 problem for those like me were unaware of a common issue and great support from Thierry of TC Electronic.

I bought my RH 750 from a fellow basschatter in April 2016 and last week the sound cut out. I knew the signal was getting to the preamp as the onboard tuner continued to work and the aux input still worked with sound through my headphones.

I contacted TC Electronic support and I resolved the issue by putting a patch lead between the effects loop send and return. I removed the lead and it continued to work ok. Apparently dirt in the return socket can cause an amp to assume an external pre-amp is connected and cut off the internal pre-amp. I since understand that this can happen to any amp with an effects loop and, whilst I expect this may be well known, it was news for me and hence this post.

A long term solution is to get it cleaned but on expressing my reluctance to send it the authorised agent in Sheffield I was advised that I could invalidate any warranty. I told Thierry that I was unsure if there was any warranty left as I had bought it second hand and had been told it was nine months old on purchase. However I thought it could be older as some of the pre-set buttons had small cracks in which I know is a common issue.

Thierry then advised me, from the serial number, that it was purchased from Andertons Music Company in early February 2014. Over twice as old as I was told (Hmmm…) but could have been worse. However even though out of warranty Thierry has sent me a full set of replacement buttons and also a set of spare knobs in case these crack and received within five working days.

Overall I consider this excellent support from TC Electronic. Thank you Thierry.

The problem with knobs is fairly common on these. TC sent me free replacements too, even though it was second hand and out of guarantee.

My RH450 died on my third or fourth gig during soundcheck. White smoke.
That was a Saturday. On Sunday I was able to get a response to my query, and they arranged for me to receive a new one at my local dealer. On Wednesday I walked in with my dead amp and walked out with a fresh one. Impressive service.

Their support team are good and very helpful - lucky really as, unfortunately, they get a lot of faults

I've not seen one fail completely but every single one we've had in the store has had to have some work done on it. Usually just cracked and/or crackly knobs and we did get one with the send/return issue as well.
