The Morley Twin Mix is a switching device, announced in March 2011 and available from April 2011, built for players who run two inputs, two outputs, or both. Morley describes it as a new tool that makes setups combining multiple amplifiers and a variety of instruments easier to manage, allowing quick and easy signal routing when using two inputs and/or two outputs without the need for MIDI switching systems1.
One output or two: how the routing works
The Twin Mix's routing depends on how many outputs you use. When both the channel 1 and channel 2 outputs are in use, each input is automatically routed to its own output channel. When only the channel 1 output is used, the Twin Mix combines both input sources to the channel 1 output destination1.
| Setup | What happens |
|---|---|
| Both outputs (channel 1 and 2) in use | Each input is automatically routed to its own output channel1 |
| Channel 1 output only | Both input sources are combined to the channel 1 output destination1 |
Each input has an independent level control, which Morley describes as being there for the perfect mix of both inputs, and each input also has its own footswitch to engage or mute the signal1.
Buffer, power and build
Rather than conventional true bypass, the Twin Mix uses Morley's TrueTone Bypass buffer circuit, which the company says is there to maintain signal integrity and tone quality1. Power comes from one 9-volt battery or an optional Morley 9-volt adapter1. The unit is manufactured in a solid cold-rolled steel housing1.
The Twin Mix is a buffered switcher, not a true bypass unit: Morley specifies its TrueTone Bypass buffer circuit for the job1.
Where it sits in Morley's switcher range
Morley has made switching boxes for decades, and the Twin Mix sits alongside the company's other ABY-style units. Players comparing it today may also come across the Morley ABY Mix, the Morley ABY Pro, the Morley ABC Pro Selector and the Morley Gold Series ABY, or the wider field of switching pedals.

Questions
Does the Morley Twin Mix run on a battery?
Yes. Morley says the Twin Mix can be powered from one 9-volt battery or from an optional Morley 9-volt adapter, so it can sit on a pedalboard or run standalone without a power supply.
Is the Morley Twin Mix true bypass?
The Twin Mix does not use conventional true bypass. Morley built it around the company's TrueTone Bypass buffer circuit, which the company says is there to maintain signal integrity and tone quality.
What is the Morley Twin Mix used for?
It is a switching device for setups that combine multiple amplifiers and a variety of instruments. It handles quick, easy signal routing when using two inputs and/or two outputs, without needing a MIDI switching system.
Can the Morley Twin Mix combine two guitars into one amp?
Yes. When only the channel 1 output is used, the Twin Mix combines both input sources to the channel 1 output destination, so two instruments can be fed into a single output, with an independent level control for each input.
How much does the Morley Twin Mix cost?
Morley set the Manufacturer's Suggested Retail Price at $129 when the Twin Mix was announced in March 2011.
Who designed the Morley Twin Mix?
The Twin Mix was designed by Scott Flesher, who commented on the design in Morley's 2011 press release announcing the unit.
