Boss TR-2 Tremolo Modification

Make your TR-2 rival any boutique tremolo. This Fromel kit upgrades the Boss TR-2 with premium components and fixes its biggest quirks — so you get a deeper, more musical throb across the whole range.

• Wider range of Speed and Depth
• No volume drop when the pedal is engaged
• LED that pulses in time with the tremolo speed

(Kit only — no pedal included.)

Will it fit my pedal? This kit works on through-hole TR-2s only. Boss began using surface-mount (SMD) boards on some pedals in 2017, and this kit will not fit those — check the compatibility image in the listing before ordering.

Which option should I order?

• Supreme Kit — all the parts plus detailed color-photo instructions. An easy project with basic soldering skills.
• Have us install — send us your pedal and we'll do it for you.

Hear it

Installing the kit yourself voids the pedal's warranty and is done at your own risk — but with basic soldering skills and the included instructions, it's an easy project. International orders may take 4+ weeks due to customs.
