The AXiom Overdrive Preamp OP-1 was designed to be the most capable, versatile, yet simple to use 100% analog overdrive pedal available.  It can go from a transparent boost to a traditionally-voiced overdrive to a high-gain preamp with the turn of a few dials.

The OVERDRIVE control delivers classic overdrive pedal tones, while the cascaded PREAMP control dials in a tube amp-like preamp section - it's like a vintage overdrive pedal and tube preamp in one.  Use it as you would a traditional overdrive pedal or as an "amp in a box" type preamp.  The sloped MID control is voiced as an American style amp below 12:00 (for "Blackface" clean or scooped metal tones), and as a British amp above 12:00 (for barking mids).  Along with carefully voiced BASS and TREBLE tone circuitry, the OP-1 can produce a vast range of light to crunchy to tube-melting overdriven tube amp sounds.  It can be clean and clear, fat, warm, tight, mild or brutal depending on how you dial it in.

The OP-1 is equally at home driving a tube amp into saturation as it is at making a sterile solid-state amp sound like a cranked tube head or a warm old tweed.  From country to blues to rock to metal, the OP-1 was designed to be the ultimate analog overdrive/preamp pedal.

  • 100% analog circuitry
  • 4558-based overdrive sections
  • MID control voiced as an "American" amp below 12:00 and as a "British" amp above 12:00
  • Matching color LED indicator so you can see which pedal is on even on a dark stage
  • True bypass
  • All AXiom pedals are individually handmade with manually screen printed graphics.  Each pedal will have minor variations that make it unique.

Super cute! If you have one dog it'll last a while. If you have more than one...buy two.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This is THE FAVORITE chew toy in our household. We have two grown labs and a 10 month old mutt and they all love this toy. They got a variety of chew toys at Christmas and this is the one that they steal from each other. That said, they've definitely managed to kill it. It's well worth the money and it's held up well to heavy chewers but four months later and we're going to have to buy a new one. It's now a stub. They managed to break off all the marshmallows about a week ago and the stick itself is more like a chunk now but we definitely got our money's worth.

Lasting 6 months in! Great smell.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This actually does smell like marshmallows which is definitely more pleasant than most dog chews!! It has held up to our power chewer. It’s a bit heavy for our smaller dog but he manages and it’s quite funny!! It’s a bit hard but that’s why it is holding up. Would buy again if this one ever wears out.

Great product
Flavor Name: Peanut Butter, Size: Medium
I have a very active, medium sized dog (heeler). I wish this product was just a little bigger but it is still a great product. I fill it with pureed meat baby food and freeze. A 2.5oz jar will fill this product about 2 times. This keeps my dog busy for a while. Its also great when she's outside on a hot day. I absolutely recommend this product and at such a great price ($6 when I purchased it) i may buy a few more so I'll always have a frozen one ready when needed.

Extra durable and hard
Flavor Name: Marshmallow & Peanut Butter, Size: Large
Much harder and tougher than most of the chews and bones I get. Too tough for my own dog, but it’s become a favorite of two other dogs in my life who are stronger chewers. Also looks adorable when they carry it around.
