A Midboost exclusive: A hand-modified Blackstar Fly 3 guitar amp having classic chorus and blue power LED
This amp had been hand-modified in the UK by Midboost to add the Chorus feature.
The video demos the chorus effect.
A buyer of my previous hand-modded chorus amp amp said on another on-line site "blackstar fly 3 with mod, sounds amazing"!

Midboost additional customizations
Added push-button for Classic Chorus which works by modulating the existing Delay.
With Chorus engaged:
- "Delay Level" adjusts the amount of chorus effect present in the original signal (3 to 5 o'clock)
- "Delay Time" adjusts the effect between Classic Chorus and Double Tracked (7 to 8 o'clock)
- Chorus Rate is internally preset for a classic 80's swirl
When the Chorus button is dis-engaged the Delay goes back to the original factory feature.
Blue power LED replaces stock red LED.

Stock Blackstar features
The Blackstar Fly 3 is probably the best and loudest guitar practice combo amp in its class!
It's also a great headphone practice amp (headphones - not included in sale - disable the in-built speaker).
And if you prefer analogue its that too (no DSPs anywhere inside). No valves (tubes) either, its all solid-state.
  • 2 channels: clean (unusually good at volume for an amp of this class) and dirty (gain channel ranging from mild crunch to classic overdrive).
    • If desired, either channel can be pushed harder with a boost pedal or hot pickups.
    • Note only one channel can be used at a time (there is only one instrument input jack). Channel selection is by a push switch.
  • ISR tone control - Blackstar's patented EQ ranging from "US" to "UK" amp tone.
  • In-built delay emulating analog tape style (darker repeats), with delay "Time" and "Level" controls.
  • External 3.5mm stereo line-level input for backing track, from phone, tablet etc. (note there's no input mix level on this channel).
  • 3.5mm headphone / line-level emulated speaker output.
  • Blackstar extension speaker (not included) can be connected via custom jack at rear, giving 6W total output.
  • Amp runs off 6x AA batteries (not included) or a DC PSU (not included), input at rear.

Important notes
  • This amp has cosmetic signs of very light use (very small 1mm surface mark near controls - does not show up in photos).
  • Unlike the video this amp has the stock Blackstar BLACK knobs (not cream)
  • The chorus is Mono (as is the original Blackstar Tape Delay effect), including when a FLY-103 extension cab is plugged in.
This hand customized amp is unique to Midboost and is not available from any other seller.

This sale does not include any original Blackstar packaging.
Size as per the stock Fly 3, approx 17W x 10D x 12H (cm)
