Used on guitar and organ for the Take Me to Church EP, as stated by mix engineer Rob Kirwan in this March 2015 Sound on Sound interview.

“Guitars I generally record using an SM57 and a Sontronics Delta. The former will go through a ‘lunchbox’ Neve 1073 copy, and the latter through an API 3124+. I’ll compress that with the ADL 100 and an LA2A. The Delta is a ribbon mic, and I use it a lot. I like Sontronics’ ribbon microphones. They give you that ribbon sound, but the problem with a lot of traditional ribbon mics is that the gain is so low that you end up bringing up a lot of noise to get them to speak. I don’t think it is worth it, whereas the Sontronics microphones require phantom power to start off with, which is pretty wild, and they are loud. They really complement the 57. The Delta mic gives the guitar lovely warmth and big bottom end, and the 57 picks up the edgy stuff in the middle. I use those two microphones on pretty much every guitar amplifier that I record."

Used for the electric guitars on Let England Shake, as stated by producer Flood on Sontronics' official "Famous Users" page.

"I use the mics all the time, be it with Editors, Orbital, Karima Francis, Foals or anyone else. The mics were used on PJ Harvey's Mercury Prize-winning album Let England Shake mainly DELTA, SIGMA, ORPHEUS and HELIOS. We used DELTAs on amps; ORPHEUSs on Polly and John's vocals, brass and ambience. ORPHEUS was our go-to mic for anything and everything: voices, snare drums, acoustic guitars, autoharp, ambience and piano."

"Finally a company that has designed microphones that are guitar amp-specific!

"The Sontronics DELTA is stunning... what a fantastic sounding mic. It pretty much sounded great right in front of the speaker with no EQ. I recently got a 1965 Sears Silvertone amp and the combination of the DELTA microphone and this vintage amp is just perfect.

"If it sounds good coming out of the amp, I can guarantee you that the DELTA will translate that perfectly, in almost 3D clarity. It blew away ribbon mics costing twice as much!"

"My discovery of Sontronics mics came about when I was looking online for a Helios Electronics preamp and I stumbled across the Sontronics HELIOS mic. It looked really cool, as did all the other mics on the website. I read up a bit more and couldn't find a bad review so was interested in getting hold of some for myself.

"I started out with a DELTA and HALO combination and the results are amazing! Not just on guitar amps either... I use them on everything. In my little studio I've been using them on my '60s Kalamazoo and my '50s Ampeg amps.

"I'm starting a band with my friend Herman Jolly, and he's been singing into a HALO. We've been using the DELTA on the acoustic guitar too.

"We've now got four HALOs and four DELTAs that we uses on the Dandy Warhols set-up live and in the studio. I've now got my eye on the SIGMA, SATURN and HELIOS mics and hoping to see a 500-series Sontronics preamp added to the range. The build quality and design are excellent, I'd recommend Sontronics to everyone... in fact, I already have!"

"Sontronics was recommended to me by Alan Moulder who had just been working with Josh Homme (Queens of the Stone Age). I tried the DELTA and SIGMA and fell in love straight away. To be able to get clarity and depth so close to the amp was amazing!

"The whole thing about Sontronics is that immediacy of things sounding great without having to do anything. The ORPHEUS has such a great bite to it and all the Sontronics mics seem to have a great natural compression without losing any clarity or detail.

"There is only praise to add about value for money, amazing customer support and the knowledge that Trevor [Sontronics MD and mic designer] cares about every aspect of the mics: the sound quality, build quality, design... and I love his ability to be as caring with the everyday consumer as he is with us professionals. And the mics look amazing!

"I use the mics all the time, be it with Editors, Orbital, Karima Francis, Foals or anyone else. The mics were used on PJ Harvey's Mercury Prize-winning album Let England Shake mainly DELTA, SIGMA, ORPHEUS and HELIOS. We used DELTAs on amps; ORPHEUSs on Polly and John's vocals, brass and ambience. ORPHEUS was our go-to mic for anything and everything: voices, snare drums, acoustic guitars, autoharp, ambience and piano. For Polly's latest album The Hope Six Demolition Project we also added an ARIA for vocals… she won't record her voice with anything else now!

"Both of those albums were the sound of Sontronics, firstly because they were used on so many sources but also, more importantly, because every time we put up a Sontronics mic it gave us what we wanted: clarity, character, purity and openness. The whole album was recorded flat, which is a tribute to engineer Rob Kirwan but also to the Sontronics mics!"

"I have DELTAs, SIGMAs, HALOs, a SATURN, ARIA, ORPHEUS, ARIA and DM-1B, and they all have that immediacy of things sounding great without having to do anything!"
