The polyphonic SYNTH9 Synthesizer Machine transforms your guitar or bass with 9 presets that were precisely tuned to emulate the most sought after, vintage synthesizer sounds ever! From searing lead synths to spacey synth pads and deep, funky, synth bass grooves, it’s all accessible.

The SYNTH9 is also super easy to use with DRY volume, SYNTH volume, CTRL1 and CTRL2 knobs that provide precise control over each preset’s parameters.

If you dig the kind of classic synth sounds made famous on recordings by groups like ELP, EVH, Kraftwerk, Joy Division, P-Funk, Peter Gabriel and more, we think you’ll love the SYNTH9.

TIPS ON GETTING OPTIMUM PERFORMANCE FROM THE SYNTH9
1. The SYNTH9 is generally best used as the first pedal in an effects chain. Place modulation, delay, and reverb effects after the SYNTH9. The unit will not perform well if placed in the effects loop of a guitar amp.

2. For optimal playability, set the guitar’s pickup selector to the bridge pickup and turn the volume knob all the way up (“10”).

3. Avoid placing a distortion or overdrive in front of the SYNTH9, which could muddy up the input signal and cause the tracking to be unstable. If you want to add overdrive or distortion, place it after the SYNTH9.

4. The SYNTH9 has a built in compressor that is active on the synth sounds at all times. We recommend you do not insert another compressor into your signal chain while the SYNTH9 is in effect mode.

I recently bought my keyboard from here instead of doing online, and I'm happy I did! Upon entering the shop you'll notice the wide variety of instruments ( especially pianos) displayed. One of the staff members helpfully talked me throught the different kinds of keyboard and gave me an idea of what sort of thing I wanted to buy , this was pleasing as it felt as if he wasn't trying to sell me something and generally wanted to help me! 👍 I ended up buying the keyboard there and then and it has been a perfect fit for me ever since! I would definitely recommend this place, even if you just wanted advice!

My family will always use Gough & Davy. Thank you guys.

Such a shame there aren’t more shops like this. What an absolute diamond of a place! Katie was fabulous sorting my daughter out with her first violin. We came from Grimsby but will be back again for all our future musical needs 🎵

I bought a Yamaha hybrid piano a few years ago from Gough & Davy and needed to replace one of the key tops. This was proving to be a logistical nightmare considering it was such a simple but integral part. Shaun stepped in and saved the day, for which I will be eternally grateful. Collected the replacement key today, Shaun couldn't have been more helpful, piano rescued - Cheers Shaun & G&D, my favourite music store for about 50 years!

I came in around a week ago and was greeted by the staff in a lovely manner. I was told to talk to Oli due to the type of guitar I was looking for. He was amazing and showed me a few things around what I was looking for. He showed me how each guitar I considered sounded and compared them perfectly for me. Couldn’t be more grateful and walked out with a beautiful guitar!

Called in to get advice about purchasing a digital piano. Shaun was so helpful and gave such good advice I returned later in the day to buy on his recommendation. Looking forward to getting home and starting my musical journey.
