Stronghold Acoustic Guitar Preamp Pedal


The biggest problem that acoustic guitar players encounter is their guitars do not sound as sweet and open when they try to amplify the signal without a good condenser microphone and a high-end studio preamp. This is sometimes described as not being “woody” or “airy.” When designing Stronghold, our primary goal was to address this issue. The results exceeded our expectations.

That being said, Stronghold is not a glorified EQ, tone shaping is just a part of what it does. It’s a professional preamp that can drive a PA easily. It can be used in conjunction with other type of effects pedals. It is a very useful tool when you go direct to a mixing console, both on the stage and in the studio. It successfully eliminates feedback issues associated with stage volume.

You can say good bye to the buried-in-the-mix level and weak tone; welcome back the full and rich acoustic sound.

For information on how we record samples, please visit Recoding FAQ page. The numbers refer to clock positions, for example Tone 12 means tone knob is set to 12 o’clock. If a toggle was set to default position, it is omitted in the title; i.e. if UltraBASS was off, there would be no reference to it. A particular toggle is only mentioned if it was on when that sample was recorded unless it is a two position mode switch.

Updated samples are coming soon!

Notice: It may take up to a minute for the sound samples to be loaded, depending on your connection. Please wait until all of them are up for the best listening experience. Samples are listed in no particular order.
