Smooth Tone and Added Punch for Your Guitar Rig

When you think of optical compression, you probably envision a massive piece of studio rack gear, not an unassuming pedal like Strymon's OB.1 Optical Compressor & Clean Boost. But don't let its looks fool you - this simple orange pedal holds the key to the powerful and polished sound you've always wanted from your amp. The OB.1 will smooth out your sound and maintain your transients, while offering subtle EQ curve adjustments and tons of extra gain to bring out the full character of your instrument.

Strymon OB.1 Optical Compressor & Clean Boost at a Glance:
  • Clean up your tone with optical compression
  • Kick off your effects chain with extra oomph
  • Strymon: a philosophy of quality
Clean up your tone with optical compression

When each note you play comes out at a consistent level while retaining the punch of full transient attack, your playing will sound cleaner and fuller than ever before. Whether you're after high-flying solos or cleaner arpeggiation, the natural warmth and smooth character of the OB.1 will add a welcome level of polish to your playing. Add to that up to 20dB of gain compensation, and you have a recipe for stronger, bolder, and punchier tone than ever.

Kick off your effects chain with extra oomph

If you're wondering what should come first in your effects chain, here's your answer: the Strymon OB.1 Optical Compressor & Clean Boost. Just the clean boost alone fuels your tone with up to 10dB of added gain, and frequency-enhancing EQ options let you bring out the best in your tone. Kick in a bit of compression with the Mid or Treble boost options engaged, and you'll swear your amp just came back from the mod shop.

Superb Transparent Compressor and Boost

The OB.1 is a fantastic compressor for a touch of transparent compression. I actually use this near the end of my signal chain (just before the delays) as an "always on" pedal with just a bit of compression to smooth out my sound and give the front end of my amp a touch more compression. This allows a bit less stage volume while still driving the power tubes into that magical space. I perform in a Pink Floyd tribute so you can imagine my pedal board is large with the whole gamut of Gilmour style effects. The OB.1 was just the ticket to smooth out the rough edges and give a heavily effected signal a bit more clarity. If you are looking for a very obvious squish, the Strymon is not the right pedal. I have a separate compressor for that purpose up front of my signal chain (an Xotic). The boost function is a great bonus and allowed me to remove my existing clean boost. The ability to adjust boost voicing to get through a live mix is very useful.

Sweet Pedal

I compared a bunch of different boost pedals and this one just had the sauce. Extremely clean and crisp sounding. Works wonders on my Bogner. Just really juices up the tone. I keep it on all the time. Also works well for DI guitar. I basically use this 100% of the time when recording or performing. Haven't really been too crazy about the boost level adjustments. I always keep it flat. I think they could re-design the pedal a little bit. It's also pricey but the sound is awesome.

Smoooth as Butta

This was the third Strymon pedal I bought after my old Boss comp took a dump. If you want a "wow" pedal this ain't it. But if you what a compressor pedal that transparently smooth's out your it is. The added boost feature is icing on the cake and the 3 band eq puts it over the top. Their stuff is built like a tank by the way.
