Hi all! I'm considering buying a 2B estim box, but wanted to ask what anyone's experience of it has been like. I currently have an Estim Electro Pebble, which I have used a bit and quite like. Reading other posts it seems that everyone suggests the 2B is not worth it. However, I am not massively into the pain element of it and I'm not going to build a DIY box or spend more on importing a more expensive model - so it's upgrade to 2B or nothing for me. I'm interested in the processing of sound files.
What I'd like to know is:-
1) I've read on other posts that the 2B generally filters out the more painful signals - is that correct?
2) are any of the Estim teases on here worth playing with a 2B box, most say they are not tested or designed for use with 2B?
Thanks for any input.

Re: 2B questions & teases
Greetings,
If you are already eyeing up the 2B, and don't care about harsh pain signals, then yes a 2B is a good bit of kit.
There are cheaper options, and there are higher quality options. But the 2B is a great unit for both direct play, or audio driven teases.
You are correct, it almost completly filters out quick signals, that are sometimes used to simulate pain.
But there are several dedicated 2B teases that use amplitude instead of frequency to drive intensity.
I'd say about 1/2 of the teases here on milo have been designed for or tested on the 2B.

Re: 2B questions & teases
what is a good, priced box that will allow you to feel all the pain files. I own a 2b but want to play the other teases

The best options a few years ago became hard to buy, the companies making them stopped taking orders.zxpguy wrote: Sat Aug 23, 2025 6:30 pm what is a good, priced box that will allow you to feel all the pain files. I own a 2b but want to play the other teases
Just not sure which of the modern commercial boxes are worth it, many have filtering.
If you are choosing based on cost, check out the build-your-own-box guides.

Re: 2B questions & teases
The MK312bt.
Plays the nuance of every pain file in the Estim Mafia and Bryci's Estim Experience.
I played them with a Estim Systems Electro Pebble (2B cousin), then played them with the MK12bt. Most notable, is Abigail's Crescendo of Pain", which leveled out at about 60% with the Pebble. Also, Abigail has a pleasure signal. The Pebble COMPLETELY ignored it, literally nothing happened. The MK312bt picked up the signal great. The line-in audio alone is worth it Unless you are going to DIY, I recommend the MK312bt.

Thanks for that, makes me more confident that it would be a good option for me. Looking forward to buying and testing itCumScream wrote: Sat Aug 23, 2025 5:47 pm Greetings,

Re: 2B questions & teases
Many teases in instructions use "left" and "right".
example:
The manual doesn't give me any hints on it.
So the question is: what letter corresponds to what side?
example:
I never understood where is "left" and where is "right" channel on my 2B? The knobs are marked "level A" and "level B" (A to the left and B to the right) but 3.5 are reversedb (channel B left and chanel A right).Left - Cock Head and Shaft/Balls
Right - Bipolar Prostate Plug

Re: 2B questions & teases
I have had the 2b for years and I had the abox (predecessor audio file driven estim box to the 2b) before it. (FyI, the 2 b is more powerful and flexible unit than the abox)
I have found the 2b to be a great unit. Solid build and good interface. A few preprogrammed signals that are fun, but the main appeal has been to use audio files. At the start I would put my spotify playlist through it and check out the utter randomness music can do to the stimming, which is pretty freaky.
Using it with teases ( I like estim tower best) is great though. The pain/pleasure sensations are good enough for what I want. I am conscious of others saying it filters and pure stereo stim boxes are better, but havibg never felt one I can't compare. One day I will try one, but for now the 2b has been perfect for what I need.
Get gel to go with, and I also recommend the mains adaptor. It really boosts the power so you can push it as far as you like.
Have fun exploring!

Re: 2B questions & teases
Generally, A is Left, and B is Right, corresponding with a stereo signal. However, often trial-and-error is needed to find what feels best for any given file, especially with either tri-phase or overlapping signals.a1exzh wrote: Mon Sep 01, 2025 9:23 pm Many teases in instructions use "left" and "right".
