The Mosky MM Overdrive is a compact overdrive pedal that Mosky describes as "Based on Timmy Overdrive", the circuit designed by Paul Cochrane1. It is part of Mosky's Mini Guitar Pedals line, and it carries three controls: Gain, Treble and Bass1. If you are looking for a small overdrive with independent bass and treble shaping, that control layout is the point of the design.
The controls: Gain, Treble and Bass
The MM Overdrive keeps the control set that defines the Timmy-style approach: drive amount on one knob, and separate low and high shaping on the other two, so you can dial the drive in without the low end piling up or the top turning harsh1.
| Control | What it does |
|---|---|
| Gain | Adjusts the amount of Overdrive1 |
| Treble | Adjusts the Middle-High frequency1 |
| Bass | Adjusts the Low frequency1 |
Having Treble and Bass as separate knobs means you can, for example, cut bass to tighten the drive and then bring treble back up for clarity, rather than working with a single tone control1.
Size, power and bypass
The pedal weighs 125g1. It runs on 9V DC with negative polarity1, and Mosky lists a true bypass switch and an On/Off LED indicator1. The maker also states the signal path is 100% analog1.
Mosky specifies 9V DC negative polarity for the MM Overdrive. The maker's page does not list a current draw or a battery option, so check your supply polarity before adding it to a daisy chain.
Where it sits: the Timmy family
The Mosky MM Overdrive is an overdrive pedal12, and at 125g it is a light addition to a pedalboard1.
The Mosky MM Overdrive is Mosky's take on the same circuit, at a mini-pedal size1. Within Mosky's own range it sits alongside other compact drives such as the Mosky Mini Screamer Overdrive, the MOSKY Green Drive Overdrive and the MOSKY MM Silver Overdrive2.

Questions
Is the Mosky MM Overdrive true bypass?
Yes. Mosky's product page lists a true bypass switch, so when the pedal is off, your guitar's signal passes through without the overdrive circuit in the way. The pedal also has an On/Off LED indicator so you can see at a glance whether it is engaged.
What power supply does the Mosky MM Overdrive need?
Mosky specifies a 9V DC power supply with negative (center negative) polarity. The maker's page does not list a current draw or battery option, so plan your pedalboard power accordingly and use a supply that delivers 9V DC center negative.
Is the Mosky MM Overdrive a Timmy clone?
Mosky describes the MM Overdrive as based on the Timmy Overdrive, the pedal designed by Paul Cochrane. The MXR Timmy Overdrive Mini, made with Paul Cochrane's involvement, is the official mini version of that circuit, so the MM sits in the same family of compact Timmy-style overdrives.
How big is the Mosky MM Overdrive?
Mosky lists the MM Overdrive at 94mm long, 39mm wide and 32mm high, weighing 125g. That compact footprint is typical of Mosky's Mini Guitar Pedals line and lets it sit alongside other mini pedals on a crowded board.
Is the signal path of the Mosky MM Overdrive fully analog?
Yes. Mosky states the MM Overdrive has a 100% analog signal path, with no digital processing in the audio chain.
