JTC Pro is designed to take the looper artist performance to one step further. It's a dual switch
stomp box pedal equipped with 6 hours of recording capability and 256 loop memories. Loop and
drum controls are separate. The left footswitch controls recording and overdubs, and starts / stops
playing the recorded loop tracks. It's also the TAP TEMPO control, you can set the drum speed by
tapping the left footswitch before you record a loop track. The right footswitch starts / stops playing
the drums and it adds drum fill during the performance. JTC Pro also offers easy-to-use start and
stop modes for making your jam sounds like an arranged song during performance, as well as one
shot mode for playing any loaded backingtrack without getting into a loop. JTC Pro has 2 outputs
and there are several output modes such as a stereo connection to two amplifiers, or you can
activate the built-in speaker cabinet simulation for Right Output to send your guitar signal directly
to PA system (or any PA monitor). JTC Pro's drum sound is a very realistic high-quality audio
sample. When you connect to any guitar amplifier or PA system, you will get a full range and
dynamic drum sound. And if you are using a small practice amplifier, there is an optional drum
frequency optimization. It makes the drum sounds more clear and helps you to get a real looper
experience with the smaller amplifiers.

of jamming with a looper pedal and you will
feel very comfortable after you use it several
times.
Auto Recording : Good for beginners.
Also very useful if the first chord is really
difficult to play. Hit the Loop footswitch, JTC

will start recording and you can stop
recording with the second hit whenever you
