Akash Barthwal: Guitarist & Studio Owner

From providing consultancy for Guitar Tone building to the complete studio set-up, the kind of support I received is unmatched.

The wonderful Custom 50 amp is something which is very hard to explain, from the subtle dynamics of the mid range to the tight bass which you feel in your chest is incredible.

The incredible in-depth understanding of technical aspects of entire chain of music production is invaluable to people like us & other musicians.

I use fender jazz for live and recording & wanted a compressor pedal for a long time but the one I liked was too costly or not available in India. I tried out & now own the PHOTOPRESS- Optical Compressor in their lab & tone was very smooth, clean & transparent although it does seem to add a nice “thickness” to the mids. The low end sounds big and full. Thank you for the pedal and making it available reasonably for us. Waiting for next bass pedal! Cheers!

Loved the Custom 50 amp. It has great headroom, good clean low mids and nice top end! Takes pedals like a dream.

InsigniaHiFi also helped tuning my amp & provided all technical suport under one roof.

Custom 50 Head + Cab

A good amp is a must for the guitarist. I’m playing guitar since 2009 and I came across so many amps, I never liked the digital amps and the one I liked (tube amps) were totally out of my budget. Last month my friend Auddie D’souza one of the best guitar luthier in India introduced me to Gaurav Kumar and that’s when I tried the amp he designed/built.

The first strum on my guitar and I was blown with the tone & the quality of sound. I never heard my guitar sounding this good. I just said WOW; and everytime I tried his amp I just wanted to keep playing. Such an amazing job by Gaurav.

And then he showed me how this amp is better in every possible ways than others. The build quality, Supreme components, Toroidal Transformer etc.

Also the amp is super versatile. With a simple patch cable you can blend two channels and get every possible tone you want. Hats off bro!!

I’ve recently booked one for myself and I’m eagerly waiting for It.

One more thing to mention is this amp is way cheaper than the same quality amps currently available in market!!

Go!! Grab one!!


This is small but effective and most practical tube amp head #customdeluxe15 I have come across last night.whoever said size matters after playing with this mini beast you will stop saying that.even if the size is small but the tone and quality out of this brilliantly design machine is just mind blowing!

As soon as I struck first notes the clarity and the response I got from it was never like before.the clean sound was just crystal clear to bring tear of joy in every guitarist eyes(they know what I am saying).as I further played little(Approximately 2 hours ?) I started realising it’s response with my guitar and pickups ,every pickup was responding so well I have #ibanez 370dx customized wiSeymour Duncanann pickups #neckpickup #vintagestacktele #STKT1N #middlepickup #vitagehotstackplusstart #STKS7 and #bridgepickup #slashalnico2pro #APH2 and #ernieball #500kpots #gibsonstrings with #jumbofrets. Neck pickup which sounded so warm and Dept of the tone I was getting (again some joyful tears ?) was wonderful.

Insignihifi Custom Deluxe 15_1As for middle pickup which is slightly hotter pickup it was giving that strong strat crisp ring to every note perfect for power blues playing.and last but not least bridge pickup which is hottest pickup among these three with the small tone and volume control it was just blowing my head over and over.such a dreamy response to each different pickup and guitar (tried American maple neck strat also which was another beauty).dreamy I said cause I have been using #marshall 15dfx solid state amp everyday and Everytime I play it, while playing I expect some dynamics out of Amp which are most of the time goes dampened.but for this mini beast it was no problem at all on even lower volume, each vibrato bend and microtones,pick attack with lot of sustain without losing any tone till the note dies off was there it was pure pleasure playing on this amp.thats why I said dreamy cause I imagined all these dynamic in my head and it was coming just as I imagined they could even say better than that. Practical for home practicing and recording purpose you will get the tone and quality you always wanted, so go try it out I’ll say Gaurav Kumar job well done bro keep doing what you doing we need people with such a innovative minds.
