Shure SM57 w/ Transformer & Granelli Mod

Shure SM57 Modified - Transformerless (TapeOp) Mod + Granelli Right-Angle Mod

Up for sale is a professionally modified Shure SM57 dynamic microphone featuring two popular mods: the Transformerless (TapeOp) mod and the Granelli right-angle body mod. This is the SM57 that recording engineers and drummers have been chasing - warmer, more open, and more versatile than a stock SM57, while retaining that legendary dynamic punch.

What's Been Modified:

Transformerless Mod (TapeOp mod): Transformer removed for ~10dB more headroom, reduced harsh resonances, improved low-end response, and a warmer, more natural tone compared to a stock SM57

Granelli Right-Angle Mod: Body angled for flush snare drum placement, keeping the mic out of the way of cymbals and the drummer - a must-have for tight kit setups

Fully functional: Operates exactly as intended post-mod

Sound Character:

Removing the transformer opens up the low end and eliminates the harsh upper-midrange coloration of modern SM57s, delivering the warm, punchy, "smack"-forward character that vintage SM57s are beloved for. The result is a dynamic microphone that sounds open and natural without sacrificing attack - perfect for snare drum, guitar amp, brass, and beyond.

Ideal Use Cases:

Snare drum (primary - the Granelli angle keeps it out of the way)

Electric guitar amplifiers

Brass instruments, drum kit (toms, kick beater)

Any application where you want a cleaner, more open SM57 sound

Condition:

Used Shure SM57, modified by me personally. In good cosmetic condition with some minor wear. Both mods have been cleanly executed and the microphone is fully functioning as intended. I have performed and sold several of these modified SM57s with consistently great feedback from buyers.
