www.ProGuitarShop.com - Diamond Pedals CPR-1 Compressor Pedal
Recording studios often use rackmount "vocal channels"; a mic preamp, compressor, and EQ all in one unit as a front end for vocal recording. The Diamond Compressor is our take on a "guitar channel". It's a dynamics and tone shaping tool for live and studio use, constructed with low noise, ultra linear signal buffering, smooth opto based compression, and a versatile "tilt" EQ that musically shifts overall frequency balance. All in a user-friendly 3-control package - just Comp, EQ and Volume.

Features:

· Vactrol opto-isolator variable resistance path as used in high end audio compressors for smooth attack and decay characteristics while preserving initial signal transients.

· Premium audio components, including 2% polypropylene capacitors,1% metal film resistors and a proffesional audio grade opamp (our signal path opamp alone costs 8 to 10 times what the industry norm uses).

· Post-compressor "tilt" EQ provides a very musical tailoring of frequency response, seamlessly transition from a darker jazz voicing to a brighter jangle, with flat frequency response at the center detent position.

· Double filtering stage in side chain to eliminate low frequency modulation while preserving fast
· compression response.

· Dual AC capacitive coupling paths for improved transient response.

· Bi-color LED provides visual indication of depth of compression.

· True bypass signal path.

· Battery or standard negative tip 9V DC adapter operation, can be powered from 9 to 24 V negative tip.

    It's intended by guitarists to give you more sustain without adding distortion, or ideally, anything at all assuming you like your tone. The kind of "squashed" sound you get as you increase compression is exactly that--the result of more compression. Technically speaking, the highest volumes are kept where they are, and the lowest ones are brought to the same level as the highest...or something like that haha.

  • @dreamofways - Close. The highest peaks are brought down and the lowest are brought up, to average out the overall levels. If you kick on your compressor with the level set at unity gain, then your signal will initially sound quieter due to the squashed peaks. This is why compressors "makeup gain" knobs.

  • Hey Andy,

    What voltage were you running the pedal at?

  • 9 volts. It can take up to 24v which I'm assuming would have enormous headroom!

  • two hundred videos,you guys are awsome!!!

  • Andy's awesome. He just pumps out the videos. We intend on doing thousands.

see all

  • What are the chords played at 2:33? Anyone??? Thanks.

  • can you give me the chords that you play at 2:33 !? thanks

  • What's that song at the beginning of all ProGuitarShop demos?

  • It's a telecaster?

  • I have a question.

    Coming from a punk and grunge rocker, can someone either send me a link or tell me about about what it would sound like if I were to put some distortion on it, or maybe plug it in to a Fuzz pedal?

  • best compressor i've ever used, and the only one i've ever liked - although i'm sure i'd like the empress compressor also. however, i've discovered that i don't really like compression, haha.

  • @ProGuitarShopDemos How about the EHX Hog pedal?

  • @ProGuitarShopDemos what compressors would you recommend for delay reverborator type swells....ambient sounds .....this seems good...are there others?

  • does this compressor work for bass guitars?

  • SO MUCH BETTER THAN "EXPERT" VILLAGE!!
