Fender Mustang GT100 for jazz

**j4zz** · 03-26-2026, 08:56 PM

Anyone ever tried one for playing jazz?

Because it is a modelling amp, these so many tones available. The three amp models I am playing with right now, are '65 Deluxe, Roland Jazz Chorus, and '65 Twin. The last one originally was created by Fender I think, and called "Jazz Clean". It is interesting because they switch the speaker cabinet to a 2x12 Supersonic.

I am adding a few effects to these models. I always add a Reverb (often Large Hall), and also Tremelo and Chorus. Fender added a Delay/echo which I am not sure I like.

In the end, having a 100 watt amp, modeling some classic real amps, allows for as clean a sound as you would ever need.

I like to set the delay so that it is barely noticeable, throw in a little compression and reverb and no tremelo nor chorus. Then play with the eq.

I have the Champion 20, which has the same amp models as the Mustang series, but with fewer effects and without ability to save presets. I think it sounds great (and I much prefer the simpler controls). I use the Deluxe Reverb voice and a little bit of reverb. I use it as my "grab and go" for gigs, jams, etc. in small spaces. I find that even 20 watts is enough. Probably not loud/clean enough for something like a loud fusion group, big band, or an organ trio with a real B3/Leslie and a loud drummer, but it hangs with any group where the overall volume level is set by un-mic'ed drums and horns.

Yeah 20 watts is quite reasonable. I gigged with a Roland Cube 30 watt for a while.

I did not know about this Chamion 20 modelling amp version. I will check it out, thanks. If the modeling allows you to change speaker cabinets, try the '65 deluxe, with the '57 deluxe cabinet. I am not sure, but I think is little bit nicer.

Yes, if I keep the delay in the mix, I keep it turned WAY down. I haven't spent enough time playing with compression. Didn't like it at first though.

As for tremolo, I don't know why more jazz doesn't use it (again only at low levels ike delay)

No it doesn’t allow you to select speaker models. It’s much more basic than the Mustang.

John, Do you think the Champion 20 would work with a full big band?

I play in one with unamplified upright piano. I don't have to be super loud for comping, but I have to get the solos over the horn backgrounds.

The drums are unamplified but, as you might imagine, not quiet.

Maybe but with a full on big band horn section you might not be able to keep it fully clean. But they also make a Champion 50, which I think would be fine.

I have just been reading about the Champion. I see now that they have aimed to make it all controllable from the front panel, including amp choice. This makes it very similar to the Roland Cube I used to use, except I expect they are using the digital amp modelling (cut-down) that is in the Mustangs. Sounded good in the youtube clip I watched.

The nice thing about all these digital amps, is of course, the weight. Even my Mustang, with a 12" speaker, is very light and small.

I brought a Champion 40 (19 pounds/8.6kg) to rock band practice for a few weeks in '24 I think, which what what finally got me to get a TM Twin. Volume wise it was surprisingly fine with another guitar, keys, bass and drums. It's my living room amp now, and the one I usually play through if I plug in later in the evening. Does almost everything and was extremely reasonably priced as well.

Didn't realise there was an amp also called a Mustang - which I why I posted the above video of me playing a Fender Mustang guitar!

But as it happens, I have a Fender Champion 40 and it's a good amp.

The Tonemaster version of the twin must be nice. I used the twin model on the Mustang for loud clean sounds, but it also does jazz.
