Problem with switching on a Rivera Chubster

The usual thing is that the knobs have to be in the correct position to allow the footswitch to work.

That is, channel switching works with the footswitch only if the Channel 1 Volume knob is pushed in. I think the boosts are the same way too.

Every now and again I forget about this and spend a whlie scratching my head wondering if a footswicth has gone bad.

 

is there any popping or noise when you switch? might be a bad relay. just for giggles, try swapping the preamp tubes around too.

 

OK the next thing to hope for is a bad footswitch. Any chance you can swap the footswitch?

 

Reverb not working might be as simple as the connections fell off during shipping. There should be RCA connectors on the chassis that go to and from the reverb tank.

 

Yeah now that the reverb doesn't work then one of the little tubes might be suspect - V4 - the reverb follower. A manual for this amp is online at:

Even if the preamp tubes don't get swapped around it's important to know they are all seated properly in the sockets.

 

Hi,
I have a few Rivera's.. On one of mine I had a similiar (but a bit different issue) in that the unit wouldnt switch channels with the footpedal.. Ended up being the foot switch connector on the amp..

In your case with the reverb not working as well, I would send it back and get your money back.. Everything is repairable by a tech, but why would you pay for it?

Could be that he can get the ebay seller to pay for local repair without having to send it back, thus saving on shipping.

Then there is the chance the ebay seller is going to claim it happened in shipping and then everyone waits for the resolution of claims by UPS or FedEx, etc.

 

Very good points and in truth the amp could have been damaged during transport. I've been very lucky on ebay in that I've only had an issue on one item and the seller refunded everything including the return shipping.

I kind of doubt it's the footswitch if one function (channel) works and the other two (both boosts) don't. But it's possible, of course.

If you have a multimeter, you can test the footswitch yourself. Set the meter to read resistance. Looking at the connector, you see 8 pins arranged in a circle with a gap plus a pin in the middle. Start with the pin on the opposite side of the gap - place one lead on it and one lead on the pin immediately to the left. Pressing the Ninja Boost footswitch repeatedly should change the resistance from a short circuit (nearly 0 ohms) to an open circuit (a huge number of ohms) and vice versa. If it does this, it's working fine.

Repeat this using the pin opposite the gap and the pin to its immediate right. This time, the boost switch should affect the resistance reading.
