29.03.2015: Upgrade 2015 - Mustang

All Mustang an Nighthawk amps are now delivered with Printed Eyelet Boards. These combine best of both worlds. The signal path is identical to the P2P board, but with the new boards control lines can be build as traces. This again increases the stability of the amp.

Mustang Printed Eyelet Boards

As worldwide novelty the Mustang can be ordered with a changeable glass bottom through which the inside can be viewed. To realize that a 6mm acrylic glass is hold in place with a 2mm stainless steel frame and ten screws. If it is necessary to put the amp on top of another one with a stray field to the top it is possible to change the glass bottom to a shielded plate.

06.02.2015: Toxic Combo

The Toxic can now be ordered as a regular amp. It will be delivered as a two channell combo with a mahogany case, tube rectification, sweet/punch-mode and a 12" WGS speaker. A switchable solo-volume is also available.

more details at the Toxic Special page.


24.09.2011: Mustang 2x12" Combo is finished

Christoph Berner's new Mustang Combo is ready to ship. The amp has been optimized to act in a semi open cabinet, as well as Christoph gets a modified fx-loop which only switches the send-signal. Because of this, echo signals still can be heard after switching off the loop.

The speakers are two WGS ET65 whicht are the perfect partner in this semi open combo cabinet. This results in heavy bass, warm mids and smooth treble without the often heard mid-peak.

Be aware of the details! The logo is mounted with nine small M2 stainless steel screws to prevent any vibrations. Also the chassis is mounted with stainless steel allen screws.

Furthermore the combo has four pluggable heavy duty castors and two bar handles.

14.02.2011: review in Gitarre & Bass

A Mustang review comes out in the next issue of the Gitarre & Bass magazine which will be available on 2011-02-18.

Here a first extract of the review:
"Boutique-Amps made in Germany? Still seldom. More then ever when focussing on self creations instead of vintage replicas. The top level is still represented by Peter Diezel. But in Swabia there is someone who is getting close on his heels. Not as far as sales figures are concerned, but in case of meticulousness and abandon."
translated from Gitarre & Bass, 03/2011
