The Surfy Industries - StereoMaker is fully buffered, transformer isolated, ABY switcher containing pseudo-stereo effects. Complementary analog comb filtering makes it possible to simulate the mixture of direct and reflected sound waves in a room in a very realistic way. 180 degrees phase reverse and ground lift helps cleanup any hollow sounds that can occur using two amps. A great, new, highly usable utility pedal from Surfy Industries.

From Surfy Industries:

An ABY pedal typically receives the signal from a guitar or other instrument and splits it into two outputs. The StereoMaker is fully buffered and packed with features like: soft touch JFET switching, transformer isolated outputs, pseudo stereo effects, 180 degrees phase reverse and ground lift.

In STEREO mode the width and volume controls are enabled to optimize a pseudo stereo sound. The PAD switch makes it possible to attenuate line level signal to instrument level. Also the StereoMaker can be used as a direct box to convert unbalanced to balanced signals becoming a usefultool for keyboard players and recording studios.

PSEUDO STEREO EFFECT (Y)
A simulated stereo effect is generated using analog complementary comb filters. This unique implementation makes it possible to simulate the mixture of direct and reflected sound waves in a room in a very realistic way. This effect is 100% analog and safe to mix back into mono, no side effects.

OUT-OF-PHASE SIGNALS
Sometimes reverse phase effects can occur resulting in a "non-distinct", "hollow sound". The reason might be that two guitar amps has been used with different number of gain stages. The StereoMaker has a built-in 180 degrees polarity reverse circuit to phase-match amps. Just pull the output plug half way out to get the reverse phase.

Great Case, Just Minor Issues
Color: Black, Size: Case for iPad (A16) 11th/10th Generation 11/10.9''
This case is an overall good case, in the sense that it does a good job protecting the tablet. It covers the entire screen with a plastic screen, which I personally like and don’t mind. It also had a kick stand and sting to hang it, which is a must for kids. My kid has not broken his tablet since getting this case, BUT he did not last very long with it on. The plastic screen protector and the front piece, made it super difficult for him to pull down his control center from the top right corner. This annoyed him so much that he ended up taking the whole case off and eventually losing it. If they could make the plastic sheet more fitted to the screen so that the issue is fixed I would give 5 stars.

A Tough Everyday Shield That Turns an iPad Into a Travel-Ready Tablet
Color: Black, Size: Case for iPad (A16) 11th/10th Generation 11/10.9''
I’m very impressed with this protective iPad case. It has a strong, rugged design that makes the tablet feel much safer for everyday use, especially for kids, travel, work, or anyone who needs extra protection. The black design looks modern, durable, and professional without being too bulky in appearance. What I like most is how complete and practical it is. The built-in stand makes it easy to watch videos, study, read, or use the iPad hands-free, and the hand strap adds extra comfort when carrying or holding it. The included shoulder strap is also a great bonus because it makes the case even more convenient for moving around. The raised edges and heavy-duty design give great peace of mind against drops, scratches, and daily bumps. Overall, this is a very useful and reliable iPad case that combines protection, comfort, and functionality in one. I’m very happy with it and would definitely recommend it.
