The Nashville Hot Mids solo boost is a limited-run pedal from Mad Professor, built as a modded version of the brand's Ruby Red Rooster. Where the standard Rooster is a general-purpose boost, this version aims its lift at the upper-mids, with the stated goal of making solos cut even more through a band1.
What it does
Guitar.com, reporting the pedal's launch in April 2020, described the intent plainly: the boost comes "with more of a focus on the upper-mids, aiming to make solos cut even more"1. The site's account of the circuit change was that "this new mod makes for a thick and sparkly lead tone as the carefully chosen hot midrange frequencies are added to the treble pot, which is now bringing up a perfect blend of presence and mids. Exactly what is needed to make your solos to be heard!"1
For a player, that places it in the family of boosts meant to sit in front of an amp or drive pedal and push a lead part forward, rather than to add gain of its own. It sits alongside other boost designs in the boost pedals category, and players who want a fuller drive character in the same brand might also look at the Mad Professor Green Wonder or the wider field of overdrive pedals.
Controls
The pedal is governed by three controls1:
| Control | Function |
|---|---|
| Master | Overall output level |
| Treble | Treble lift, now blended with hot midrange frequencies per the mod1 |
| Boost | Boost amount |
Availability and build
The Nashville Hot Mids was announced as part of "a new limited run of custom pedals" and was described as available until further notice rather than as a permanent catalog item1. The pedals were hand-modded at the Mad Professor headquarters in Finland1. Guitar.com listed it at €208 at the time of the announcement1.
As a limited run announced in April 2020, the pedal may not appear in regular dealer stock. The standard Ruby Red Rooster remains the reference point for the unmodded circuit.
