I’ve owned the EHX switchblade deluxe pro and it really affected the tone and volume levels even when set to “unity” gain. It also added extra noise, hiss and a high frequency response. I believe it’s due to all the different input and output impedances of the circuit. I have gut shots if anyone interested. It’s mostly all smd though so it probably wouldn’t help. Hopefully the tri parallel isn’t a similar circuit.
I can also provide gutshots of the x blender if anyones ibterested. I believe I have gut shots of the old barge concepts vbjr as well.
