Fender Mustang GTX50 Settings Guide

The Mustang GTX50 is Fender's flagship modeling combo — 50W into a 12" Celestion speaker with 50+ amp models, 100+ effects, built-in tuner, and Wi-Fi connectivity for the Fender Tone app. It covers clean to high-gain and is the most practical single-amp solution for players who need multiple tones without a pedal board.

The best Fender Mustang GTX50 settings start with: Amp Model at 3/10, Gain at 5/10, Volume at 4/10, Treble at 5/10, Mid at 6/10, Bass at 5/10. Adjust from there based on your amp, guitar, and room volume. For Blues: Amp Model 2/10, Gain 4/10, Volume 4/10, Treble 5/10, Mid 7/10, Bass 5/10.

Settings by Genre

Blues
Amp Model2
Gain4
Volume4
Treble5
Mid7
Bass5

Select the 65 Deluxe Reverb or 57 Deluxe model — pushed Volume with moderate Gain on the Deluxe model produces the Fender touch-sensitive breakup that blues tone requires. Mid at 7 keeps the tone forward and cutting in a band context.

Clean Funk
Amp Model1
Gain2
Volume5
Treble6
Mid5
Bass5

The 65 Twin Reverb model at low Gain and higher Volume — maximum headroom for single-coil funk playing. Treble at 6 provides Stratocaster snap. Add compression from the built-in effects chain for rhythm funk playing.

Metal
Amp Model8
Gain8
Volume4
Treble6
Mid4
Bass7

High-gain American model at maximum Gain — the GTX50's metal models are based on Mesa-style circuits. Scooped Mids and boosted Bass with Treble at 6 produces the modern metal character. Use the built-in noise gate effect.

Classic Rock
Amp Model4
Gain6
Volume4
Treble6
Mid6
Bass5

British model (based on Marshall JCM800 or JTM45) at moderate Gain — the GTX50's British models capture EL34 character reasonably well. Don't scoop the Mids on the British model; they provide the forward cut of classic rock rhythm tone.

Tips & Common Mistakes

  • The Fender Tone app (iOS/Android) via Wi-Fi provides access to a library of artist presets and community patches. Downloaded presets can be edited within the app and synced to the amp. It's the most practical way to build a preset library quickly.
  • Use the GTX50's looper (built-in) for practice — record a rhythm loop, then solo over it using the A/B channel switching to shift between rhythm and lead tones mid-loop.
