Hi
I have just taken ownership of a Fender Mustang floor.
I have a Boss ev10 expression pedal. Can I use this instead of the EXP 1 expression pedal?
I would like to use it purely as a volume control and control all the other parameters with the `on-board` foot pedal.
Many Thanks
Stux

P.S. Im using the Mustang floor into the front end clean channel on my Marshall DSL 100 and Marshall 1960ax cab. Sounds pretty cool.

This sort of question has been asked and answered many times in this forum. In brief, no, this won't work.

My understanding of the Boss EV- range of expression pedals is that they carry control signals specific to the Boss/Roland equipment to which they are designed to connect. These are different control signals than Fender use in the Mustang range. Further, the EV- pedals don't (I believe) directly process audio signals, so you can't use them inline with your guitar signal. Although I'm not particularly familiar with the Boss EV pedals, so you should check whether they can act as an inline audio volume pedal (see 2 below).

To achieve what you want to do, you have two options.

1. Buy a Fender EXP-1 expression pedal and connect this to your Mustang Floor (to the dedicated 'EXP-1' socket on the back of the M-Floor). You now have two expression pedals; you can configure one to control volume and one to control other effects. Note: the EXP-1 connects to the dedicated socket on the M-Floor, it does not connect to the (guitar) input of the M-Floor, and you do not put it inline with your guitar signal; I emphasise this as this point seems to confuse a lot of people.

2. Buy a conventional analogue guitar volume pedal - connect your guitar to the input of this and connect the pedal's output to the input of the Mustang Floor.

Connection via the method above would behave in the same way as turning down the volume of your guitar. For most of the pedal travel it would only clean up any overdrive used in the FLOOR.

The boss expression is pure analogue. Nothing digital whatsoever

This is true. You didn't specify what type of volume control you wanted. From the above, it sounds like you want a volume control post-effects. In this case, you still have two options. Either use the EXP-1 and configure it to control an appropriate volume setting (there are lots to choose from, depending what aspect you want to control, at what point in the signal chain!). Or use a conventional audio volume pedal in between your M-Floor and your Marshall amp.

That may be true, but that doesn't mean it will work with the M-Floor. It either needs to be an inline volume pedal (which I don't think it is, but you need to verify that as you're the person who has it in front of you), or it would need to send the same control signals (whether analogue or digital) as the EXP-1 - which I'm pretty certain it doesn't.

The only problem with the volume pedal after the mustang would be loss of the ability to swell using delay.
It needs be inserted after the pre-amp/stomp and before the time based effects.

Agree you can't do this with a volume pedal after the Mustang.

So I think your only option is the EXP-1.

Bummer :lol:

@Scott UK
Do you know where the insert point of the Floors FX loop is ?

Yes. This too is discussed at length in this forum. Briefly, the fx loop comes right after the guitar input, before any of the DSP.

So no, using the M-Floor's fx-loop isn't an option to achieve what you want (I'd already thought of that and didn't suggest it because of the fx-loop position), as you want a volume control (as far as I can tell) after your overdrive and amp-modelling effects, but before your reverb and delay effects. That is, you want your volume where everyone wants their volume :-)

The M-Floor's fx loop is in the wrong place to achieve that, which a lot of people have moaned about. There's an obvious implementation reason why it's where it is, but that doesn't help solve the problem. The only useful purpose the fx-loop serves is that you can switch the whole loop on/off with one footswitch button (rather than having to turn effects off individually). In terms of audio signal chain, putting effects in the fx-loop is exactly the same as putting them between the guitar and M-Floor input.

I'm afraid I really think your only option is the EXP-1.

Ah well, worth a try.
I think i will stick to using the inbuilt pedal for volume control.
Will keep an eye out for the EXP1 second hand though
Thanks for your time and knowledge Scott !!

It appears the built in volume pedal is not allowing the delays to keep repeating (swells) when I back off the volume via the pedal,
Any ideas ?
