Why is the Dual Pre different?

The Dual Pre has been studied thanks to the contribution of some professional bass players who helped us to identify the main characteristics that a bass preamp must have to be really complete.

It was born to be perfect during your recording sessions, (from your home recording bass lines to professional studios sessions) but the result was a preamp perfect also for live Gigs.

Here's what our Dual Pre can do:

  1. 1) Allows you to have two separate channels, both with the most complete equalisation section present on this type of products (4-band eq with 2 selectable frequencies on the medium-low and 2 on the medium-high, boost filters for low and high frequencies)

  2. 2) Allows you to have a channel with an integrated professional overdrive (Blend, two distortion modes and high pass filter)

  3. 3) Allows you to switch from one channel to another with two different instruments or with the same instrument, but also to mix the two channels in a single output to your amplifier to have an extreme saturation but which preserves all the definition and attack of the clean channel

  4. 4) Allows you to send these two signals even separately to the P.A. through two D.I. outputs a function that in the studio will allow you to simultaneously and separately record a clean and a distorted track (or if you want to mix them in a single D.I.).

  5. And through the "parallel output" you can have a further output with the sound of your untreated instrument giving the studio engineer a lot of material to work with and without forcing him to connect an external D.I. box

  6. 5) Allows you to have a high quality compressor with the possibility of adjusting ratio, threshold, release and volume, not the single compressor pot that you usually find on some bass preamp

  7. 6) Allows you to have an integrated tuner

  8. 7) Allows you to have a headphone output with its own separate equalisation (volume, treble and bass) that you can use as a monitor if necessary or to study when you are traveling and play along thanks to the aux in that will allow you to connect a smartphone or a media player

  9. 8) Allows you to take advantage of all these functions through four separate footswitches in order to avoid complicated combinations or unmanageable manual switches during a concert. And in addition, you can choose two different switching modes between the two channels (channel 1/2 and channel 1 + 2 or channel 1 and channel 2)

  10. 9) Allows you to have your Gr sound always with you even when for transport needs you use external Backlines, a real portable Gr Dual in a bass pedal.

GR Bass Dual Pre:

The most complete Bass Preamp in the World

Pure Sound, Made in Italy

We are proud to present the first pedal
born in the GR family, the "Pure Drive".

The Pure Drive is a decidedly versatile Preamp designed for the most demanding bass players but suitable for everyone thanks to its ease of use that allows you to always have all the characteristics of the GR sound in ultra-compact size.

The Pure Drive is equipped with a 4 band eq with 4 selectable frequencies on the mids and deep and bright filters.

Furthermore, it is completed by an "Overdrive" section which, with its volume and dedicated drives, will allow you to obtain light saturations up to massive distortions.

The Pure Drive is also a professional tuner with display and a D.I.
All the components are carefully selected to offer a top product. It is completely made in Italy and is designed and built by a bassist for bass players.
