Here is a list of the effects available for rent from Thermionic Studios. Every pedal listed here is one that we have in inventory (or have all the parts for and are in the process of assembling) and available for you to try out. We believe that if you're interested in tone-shaping for yourself, it might be nice for you to find out what you like before deciding that you're going to invest a lot of money in obtaining such pedals for yourself.
We have a few things listed along with the companies here for clarity - here's an explanation:
- (Production pedals): This means that this company builds and sells full working pedals. Just buy, plug in, and play
- (Built-from-PCB pedals): This company sells (mostly) only printed circuit boards (PCBs). We have purchased the PCB, and the necessary electronic parts to assemble this pedal.
- (Kit pedals): This company sells kits that consist of the PCB, the enclosure, and all the electronics necessary. You're on the hook to assemble. Sometimes, despite the fact that the company offers primarily kits, low customer interest and lack of sales volume of certain pedals will prevent a company from putting together certain kits. In those cases, it's not uncommon for the company to offer just the PCB. When we believe there's an interesting pedal and only the PCB is available, we'll still buy the PCB and source the necessary parts.
We also have notes, where applicable, that are specific to each pedal - here's an explanation:
- (pcb): We purchased this pedal as a PCB only and have sourced the parts to build it.
- (kit): We have purchased this kit and have assembled or are assembling the pedal from the kit.
- (modified): We purchased this pedal and have purchased and have applied, or are applying, a modification that we feel benefits the pedal.
- "nothing": Where there is no indicator, this is simply a production pedal that we've not had to put any additional work into.
Where we have "(discontinued)" listed for a pedal, it means that the particular pedal that we have is no longer being produced by that company. For example, we have the Dunlop Uni-Vibe listed as (discontinued), yet if you go to JimDunlop.com, you'll see that they offer a uni-vibe pedal for sale. What we mean is that the VERSION of Uni-Vibe that we have is the older lamp-controlled Uni-Vibe with the original architecture, not the re-worked (non-lamp) version that fits into the smaller "deck-of-cards" sized pedal that is now available.
In other cases we specify, "(out of production)" meaning that no version of the pedal is made anymore - it's out of production, and there is no intended replacement. This pedal has reached end-of-life. This could happen because the company has decided to stop making the pedal completely. It could happen because the pedal company is out-of-business. A good example of this would be with the Build Your Own Clone Armstrong Twin kit. We spoke to BYOC and it was the case that not enough people were buying the Armstrong Twin for them to make it a product continuing forward. So we got one of their last PCBs for it.
With respect to pedals, and in keeping with our amplifier philosophy, please note that we ALWAYS attempt where ever and whenever possible, to collect pedals that we believe are artistically meaningful and musically significant. Our goal is to help you get to the "tone-nirvana" you either have in your head, or are perhaps still seeking.
Many of the pedals (production pedals) we have are no longer available at all (like our Electro-Harmonix Holiest Grail, or our Damage Control pedals) and must be long-sought on eBay and other used-equipment sites like Reverb.com. In most cases, clones are not available, and when another such pedal will be available for sale is questionable. Once these pedals break and can no longer be fixed, unless we can source others, they will likely be gone for good.

Jim Dunlop, the company (as opposed to the man), is probably best known for its association with (ownership of) the Crybaby Wah-wah pedal, and both the MXR and Way Huge brands. That said, it was Jim Dunlop who took the wah-wah pedal from the edge of obscurity, purchased the business and rights for the wah-wah from Whirlpool Manufacturing in the mid-1980s, and kept the legacy and the effect going. Dunlop is also known for reissuing the Dallas-Arbiter Fuzz Face as well as a version of the Roger Mayer-developed Jimi Hendrix Octavio effect.

MXR is a brand that was started in the late 1970s. MXR obtained much of its notoriety by having been associated with Eddie Van Halen and his early artistic output. However, MXR has long been used and loved by many professional musicians. After MXR went out of business in the 1980s, the rights of the company were purchased by Jim Dunlop who has carried on the promise of MXR as a maker of premium analog-electronic pedals.
