The Caroline Guitar Company Parabola Pawnshop Edition is an amp-style tremolo with a higher-gain preamp built in. It offers two tremolo modes, Filtered and Amplitude, Fast/Slow ranges, and a Havoc footswitch for maximum Depth and Speed1. Where the standard Parabola is Caroline's tremolo on its own, the Pawnshop edition adds that preamp section, which Guitar Pedal X's Stefan Karlsson said delivers more of a Magnatone feel1.
The controls
The Pawnshop Edition carries six knobs and switches on its top panel, plus two footswitches1.
| Control | What it does |
|---|---|
| Volume | Sets the pedal's output level1 |
| Gain | Drives the higher-gain preamp section1 |
| Mode | Selects Filtered or Amplitude tremolo1 |
| Range | Selects Fast or Slow speed range1 |
| Depth | Sets how strong the tremolo effect is1 |
| Speed | Sets the tremolo rate1 |
| Bypass footswitch | Momentary and latching bypass1 |
| Havoc footswitch | Maximum Depth and Speed while engaged1 |
The two modes come from the Parabola design itself. On the maker's product page for the Parabola, Caroline describes the choice as "the classic, dramatic amplitude modulation (AM) you might expect, or a filtered modulation (FM) that is subtle"2. Karlsson found the Filtered mode subtler, with a different timbre, and said he loves the classic Amplitude voicing, with the Filter option giving a slightly subtler, different take1.
The Havoc footswitch is the pedal's second switch. Pressing it pushes Depth and Speed to their maximum, and Karlsson described what that feels like in use: "you get a moderate pulse as a default - with a more intense trill when you hit the second footswitch"1. In a later piece he added, "I particularly enjoy using the Havoc Footswitch on the Tremolo - for a little fluttery accent every now and again"3.
How it differs from the standard Parabola
Caroline lists the Parabola in two models, STANDARD and PAWNSHOP, on its product page2. The difference is the preamp: the Pawnshop edition delivers more of a Magnatone feel with a higher-gain preamp section compared with the standard Parabola1. That preamp has since gone further in Caroline's lineup: the company built on the circuit from the Pawnshop Parabola and the Meteore for the stand-alone Aaron Graves overdrive, which Guitar Pedal X described as warm and versatile4. Players who want the gain stage without the tremolo can look at preamp pedals and overdrive pedals more broadly.
Availability
The Pawnshop Edition is a limited run that has largely passed through the market. As of May 2026, Karlsson reported it long since sold out on the Caroline Guitar site, with a handful of units remaining on Reverb.com, all still new and going for $2191. He also noted the edition was mostly a USA-based special edition, with few units shipping to the UK1.
The Pawnshop Edition was reported sold out on Caroline's own site as of May 2026, with only a few new units remaining elsewhere at $2191.
What reviewers said
Guitar Pedal X's review is the main published verdict on the Pawnshop Edition. Karlsson's overall view was that the Parabola is still a standout within the tremolo category, even though it does not have the extended waveform coverage and expansive features of some other tremolos1. On the preamp specifically, he wrote that "the extra gain oomph in the preamp section makes it a really worthy acquisition"1.
"the Parabola is still a standout within that category - it doesn’t have the extended waveform coverage and expansive feature set of some of my other ones - but is sounds consistently superb."
For settings, his preferred starting point was Volume, Depth and Speed at 2 o'clock, Gain at 9 o'clock, Mode Amplitude, and Range Slow1. In a follow-up comparing Caroline's analog modulation pedals, he ranked the Pawnshop Parabola second of the three, behind the Arigato and ahead of the Somersault3. He also uses the pedal himself, writing that he has really enjoyed using the core voicing on his Parabola Pawnshop Tremolo4. For other options in the effect, see the site's tremolo pedals page.

Questions
What does the Havoc footswitch on the Parabola do?
The Havoc footswitch pushes the tremolo to maximum Depth and Speed while it is engaged. Guitar Pedal X's reviewer described the effect as a moderate pulse as the default, with a more intense trill when the second footswitch is hit, and said he particularly enjoys using it on the tremolo for a little fluttery accent every now and again.
Is the Parabola Pawnshop Edition still available?
As of May 2026 the edition was long since sold out on the Caroline Guitar site, with a handful of remaining units on Reverb.com. Those remaining new units were going for $219. The reviewer understood the Pawnshop Edition to have been mostly a USA-based special edition, with few units shipping to the UK.
What is the difference between Filtered and Amplitude mode on the Parabola?
Amplitude is the classic, dramatic amplitude modulation (AM) you might expect from an amp-style tremolo, while Filtered is a filtered modulation (FM) that is subtler. Guitar Pedal X's reviewer found the Filtered mode subtler, with a different timbre, and said he loves the classic Amplitude voicing while the Filter option gives a slightly subtler, different take.
Can the Parabola bypass switch be used as momentary?
Yes. The Parabola's bypass footswitch works in both momentary and latching modes, so you can either hold it for a temporary effect or press and release it to switch the pedal on and off as usual.
Who uses the Caroline Parabola Pawnshop Edition?
Stefan Karlsson of Guitar Pedal X uses one and wrote that he has really enjoyed using the core voicing on his Parabola Pawnshop Tremolo. In a later piece ranking Caroline's analog modulation pedals, he placed the Pawnshop Parabola second of the three, behind the Arigato and ahead of the Somersault.
