Although Gillespie and Mani allude to a mountain of pedals and gear housed within Bonker, Innes claims to not remember what any of it's called. But whether it's coy secretiveness or early signs of Alzheimer's, Innes lets a few cats out of the bag. His favorite box is the Electro-Harmonix Micro Synthesizer. “It's funny,” Innes says. “It's made for guitar, but it's brilliant on everything apart from guitars. It makes guitars sound crap, and it makes vocals, drums and anything else sound good. You just have to experiment and use your pedals for what they're not meant to do. You're not meant to play a guitar through a synthesizer, so you should do it.”

JM: When it comes to guitars and amps, what sort of set-up do you use?

AI: I just use anything that's lying about and it depends on what I am doing guitar wise. Since the Vanishing Point [1997] record, I've been using this Mexican-made Fender Stratocaster. I had originally gone shopping to buy a wah wah pedal but came out with this guitar instead. I believe it's not what guitar you use but what's inside your head that matters. Amp-wise, I only use a very small Fender Tweed for recording most of my parts on. It's only got one input and a volume control and that's it. I just stick a microphone in front of it and it sounds great. I'll use anything I can get my hands on when it comes to effects. Recently I got this Japanese fuzz box that you can mess up the sound of the fuzz with, but the instructions are in Japanese so I still don't understand how to use it!

JM: Speaking of effects, it seems one of your favourite pedals is a Electro-Harmonix Micro Synthesizer?

AI: They're great. It used to inspire me to come up with so many riffs. I think we used to put everything through it, like the drums and vocals.

Bruce Bouillet mentions in the video "My Studio Setup and Guitar Sound" that although the Electro-Harmonix EH-7900 Micro Synthesizer is not currently on his pedalboard, it is something he uses regularly.

In a 2012 Instagram post, Paco Huidobro features the Electro-Harmonix EH-7900 Micro Synthesizer on his pedalboard.

In a 2016 live performance, Andy Falkous was photographed using the Electro-Harmonix EH-7900 Micro Synthesizer. The image is available on Getty Images.

In the Premier Guitar "Rig Rundown" video for Dr. Dog, Scott McMicken discusses his customized Electro-Harmonix EH-7900 Micro Synthesizer, which he painted silver, at the 28:50 mark.

Sometimes used live as an envelope follower for synths, kazoo and samples. In studio we use it to process guitars.

So what stuff gets you through those studio sessions?

In the studio I use so many pedals - the entire new Ibanez range, a micro synth, loads of old sixties pedals.

Juanma uses this into many ways, as an octaver, as a wave processor, weird fuzz... is the first pedal in his signal chain. Juanma explains the pedalboard he usually used in this radio/internet show called ''Masterclass 6x3'' by Sergio Bustamante in Radio 3, the spanish public music radio.

In this Instagram post from Rodrigo's personal instagram page, we can see he is using the Micro Synthesizer pedal with Saves the Day and Into It. Over It.

In a September 28, 2017 Instagram post, Silvia The Witch shared that she incorporated the Electro-Harmonix EH-7900 Micro Synthesizer into her pedalboard for a short period.
