I have a Fender G-DEC Guitar amp and it has an output for recording, can I connect it to the BOSS MICRO guitar input? The Fender amp has many rhythm functions which I am very familar with, besides it has plenty of built in guitar amps and various effects. Lionel

Get inside it and check the connections to the plug especially any shielding / braiding. Resolder the connections.

Hello Alan.
Yes you can connect your ME-25 to the BR-800, there is no risk to damage any. it is simple, you may use both outputs of the pedal and send them via two normal 1/4 plug guitar cables to two of the channels of the DR (i.e. ch 1 & 2) to avoid an initial saturation of the recording preamp, set the input sens pot at minimum and the sliders very close to minimum as you try playing and looking the levels on the display and adjunting them to the optimum.
To connect the DR to an amp you should use the pair of RCA jacks named LINE OUT (R & L) depending of the amp you have there might be the need for a conversion cable or plug adapters. The out put of the DR is stereo, and if you want to use a guitar amp, commonly mono, you should mix both channels to send them to one input, this can be done by putting two 10 kohms resistors in series with each channel output and joining the other end to the input.
Good luck and best wishes

there should be an input, and an output on your pedal, the connections should be : guitar to pedal input, pedal out put to amp input.

There is a small chance it "could" but more likely you would just overdrive the input stage to clipping.

You can try it- you need to keep the viltage input to the amp at 1 volt peak to peak or less, or you run the risk of clipping. You should use shielded cable, as you may also pick up other noise along that cable.

You will use microphone with balanced XLR connector into the XLR mic input. Note, the ALpha does NOT have phantom power so you cannot use condenser mics.

A guitar can be plugged into the hi-z instrument 1/4 inch jack on the left front of the unit.

To use the line 1/4 inch inputs you will use BALANCED TRS 1/4 inch cables from your source.for these channels. The level on these needs to be line level.

The line outs are for sending audio out to an amp. There appears to be RCA outputs you can use as well.

I am not sure what you mean by making your "amp record"... An amp PLAYS the audio, usually into a speaker.

If you are trying to play a guitar through your amp AND record, then you will connect your guitar to the Alpha, the amp input will have a cable from say Line 1 OUTPUT and when recording wou will have the echo feature on so your guitar is passed through to the amp.

Plug your guitar into the input and a cord from one or both outputs to the inputs of whatever you are using. Meant to be run in stereo for best sound. Two guitar amps?

You can plug the output of the gt10 into the "power amp in" jack of the Fender. This bypasses the preamps in the Fender but uses a buffer amps in the Fender to drive the power amp. Please note that the reverb is STILL in the circuit when you do this. You can turn the reverb to zero if you wish to disable it.

You are probably overdriving the pedal. Reduce the amplitude INTO the pedal and AMPLIFY it more AFTER the pedal.

When digital conversion is done from the input and the input exceeds the input voltage capabilty of the A-D convertor, it effectively "flattops" just like your overdrive on a guitar amp.

Your guitar may be very "hot" having high output. One needs to keep the signal levels in-bounds of what the hardware can handle at EVERY point.

from reading instructions when you record channel 1 and 2 you are recordind channel 1 in stereo so you only recorded channel 1 try rcording on chanel 3 for vocal hope this helps

Run a jack from your guitar to Input R Mono on the pedal.
Run a jack from Output R Mono on the pedal to the input of your amplifier.
There is a switch for guitar or Bass. Put the swich on guitar
You do not need a preamp to use this pedal.
Hope this helps,
