Digitech JamMan Stereo Looper Review

This complex sampler was one of the first live looping tools from which the notion of the loop pedal evolved. Guitar pedal giants DigiTech termed their string of looping pedals following this older legend.
Four hardy footswitches take up most of the surface. One begins playing or recording loops, other works as a stop switch that can also be employed to adjust the tempo.
Speaking of those card banks, the pedal includes 99 of them, each one capable to keep a loop, for a total of up to 35 minutes of recorded loops. As though this was not sufficient, the pedal carries an SD card which grants another 99 banks. This is a signature characteristic of the JamMan that makes it easy to transfer, upload, and also download loops to your JamMan.
. The back rows of controls may seem complicated at first glance, but the lights and labels make it easy to understand what exactly does.
Plugging one in expands your controls for loop tempo and reverse playback, and gives you immediate undo/redo functions.
Right off the bat, you may have noticed the similarity in look between the JamMan and Boss’s RC-20XL. You are certainly not alone. The RC-20XL came out in August 2004, and the JamMan a year later, to the month. This leads to a lot of competition between the two pedals, and they are in many ways easily comparable. DigiTech has since released a couple of new pedals, the JamMan Solo, the JamMan Stereo, and the Jamman Delay, but then again, so has Boss with it’s RC-3x series.
The manufacturing competition between Digitech and Boss does stand out, and they’re alike in more ways than just looks. In actuality, both manufacturers offer us loopers with a lot of the very same functions. The key to choosing between the two is simply to establish the differences and take your choice.

Memory To store your loops the JamMan gives you 99 places, which are saved on a Compact Flash card. With the device you get a 128MB card, which is good for around 24 minutes of recording time, but you can get cards of up to 2GB, which provide over half an hour of storage period.
This is one of the principal differences between the JamMan and the RC-20XL, and it’s one where the JamMan really does exceed the competition. The RC-20XL only offers sixteen minutes of recording time, and there is no USB connection for remote storage.
Another footswitch can be used to stop playback, clear what you’ve recorded and also to tap out the tempo. The”Tap Tempo” feature is an impressive one, enabling you to change the tempo of files without changing the pitch. Tapping the tempo can be vital if you want to play together with one of those pre-made rhythm sounds. You can either tap the tempo on the pedal or on it’s button on the upper section of the pedal. This is as simple as it sounds, a light blinks to show what tempo you’re tapping out, and after it is right, just don’t tap anymore.
Features Aside from a slick blue metallic casing, the pedal functions as a stereo device with two inputs and a pair of outputs.
We are dealing with a true bypass pedal here, which is particularly significant with a loop pedal.
The item weighs at 10.6 ounces and includes a total size of 4.6 x 3.2 x 2.1 inches.

Yes, the JamMan Stereo has this attribute. Loop-to-loop queuing is when you are playing a current loop/slot and you change to another loop/slot without quitting the current.

However, as pointed out in the comments of this video, by Albert Amman (who devised an accessory for the JamMan) when there’s nothing pre-recorded from the slot you switch to then it will only continue to play the current loop. This has also been noted in other forums.

You can only switch back to the previous loop if you’ve saved it by pressing the”Shop” button (not a footswitch) before switching to a different loop.

Also, there’s an after-market footswitch on Ebay that you can use to press the”Store” button with your foot (connection ), it’s known as a FABE.

With the DigiTech JamMan Stereo, can I record and play unique sections of a song (verse, chorus, bridge) all during a live performance while not using my hands (pedals and footswitches only)?

Can I go from recording directly into overdub with the DigiTech JamMan Stereo?
Yes, it is possible to go directly into overdub with the JamMan Stereo but it will require a double tap of the Rec/Overdub footswitch after you have recorded the first loop.

Can I undo/redo the last overdub to change the tune or eliminate a recording error with the DigiTech JamMan Stereo?
With the JamMan Stereo, you have the ability to undo the last overdub and redo the last undo.

Is the DigiTech JamMan Stereo a Great looper for live performances on stage?
We would urge other loopers for live stage performance. This version is better for home in our opinion. We like this model’s performance for writing new songs, editing, porting to a DAW, practicing, learning and movie performances.

Why is using a DigiTech JamMan Stereo better than just using an iPhone or iPad program?
There’s quite limited functionality using the iOS established loopers in comparison with the DigiTech JamMan Stereo. Nevertheless, these programs are quickly improving. With additional hardware (microphone, Bluetooth control pedal, etc.), these setups might begin to look attractive. Please see our iOS app setup info. With regards to live performances, bringing an iPad or iPhone on point may feel more like a DJ performance, but it’s not going as far as bringing a laptop. Additionally, the OS may be more predictable and stable in contrast to an entire computer or workstation. Thus, we believe iOS based loopers will be stage-friendly than notebooks, but much less stage-friendly as pedals/stompboxes in the foreseeable future.
