Amp & Effects pedal compatibility

Elvistheblue · #1 April 21st, 2007

Hello everyone,

I have recently purchased Digitech RP250 effects pedal to compliment my Vox AD15VT amp.

Does anyone know if there is a compatibility problem with these two products??

Is it because the amp is already a modelling amp and adding to it is just not the done thing??

Any advice would be greatly appreciated.

Cheers.

Just set your amp to a clean model and you should be good.

Try it with headphones, no amp. Good for late night practices.

Like Fly said - set the amp to a clean model and turn off all the onboard effects. I use a Boss ME50 with my Roland Micro Cube and it sounds fine.

Set it to "Boutique CL" and press the "bypass" button (don't press the "tap" one). That's the cleanest sound you can get with that amp. Your effect processer should have no problem then.

I know this cuz I have the same amp.

To expand a little further on it - if you use a distorted amp model and then pile more distortion on from your Digitech pedal, you'll end up with that "jar of bees" sound - it's just too much. Using the amp models and onboard FX are great as long as you're using them for a whole song - but if you're playing a song where you need to switch between clean & dirty (or dirty & dirtier), or add chorus, flanger, etc. in only a certain part of a song, that's where your pedal comes in...it's a lot easier than trying to turn the knobs/push buttons on the amp in the middle of a song!

You can actually get some decent sounds out of the Digitech RP pedals if you play with the presets - most of the included ones are pretty over the top. Check out the forums at Digitech's website - a lot of users have contributed their patch settings for songs, artists, etc.

Thanks for all your responses.

The trouble I am having is that the RP250 isn't picking anything up from the guitar. It doesn't even register anything in tuning mode.

I can get the RP250 drum machine to come through the amp but no guitar.

I am now starting to think there is a problem with the input socket on the RP250.

Maybe try the simple things first... have you tried a different lead or is the guitar active and in need of a fresh battery?

Elvistheblue · #9 April 22nd, 2007

Guitar and leads are fine.

Guitar works through the amp with both leads.

Check the volume setting on the RP. It may be set way low.

Check the power supply as well, must be powered...

Also check the documentation, make sure there is not a setting you are missing.

Elvistheblue · #12 April 22nd, 2007

Thanks for the replies people, but I have checked all this but to no avail.

I think I have narrowed the problem down to the wrong power supply adaptor.

I am using a 230v one and I think it needs to be 240v.

I will get another adaptor and give that a go.

thanks again though.

That could do it - my Digitech JamMan got real goofy and refused to work when I tried a different power supply than the one it came with. Hope the answer is that simple for you!

Elvistheblue · #14 April 23rd, 2007

I did it.

I was using an AC/DC power supply when in fact the Digitech RP250 requires an AC/AC power supply.

Everything is great now. It has given my already decent amp a new lease of life. Fantastic.

Thanks for all your efforts to anyone that responded.

Cheers,

How in the world you got the drum machine to play with that P/S is beyond me. I'm surprised that the RP250 would do anything with a DC supply when it needs AC.
