Подскажите пожалуйста, правильно ли я понял:

According to the Haze 15 schematic, here's the equivalent values:
Haze 40 C73 (220pF), overdrive volume cap = C59 (220pF) in the Haze 15
Haze 40 C72 (47pF), bright cap = C58 (47pF) in the Haze 15
Just looking at the schematic, I'd think you'd get similar results doing these mods to the Haze 15. Try lifting a leg of C59 first. If you need more brightness at lower overdrive gain settings, increase C58 by paralleling a 820pF to 0.001uF cap across the 47pF cap already there.
To get the overdrive channel a bit brighter, here's what you do:
1. C73 is a 220pF cap placed in parallel with the element of the overdrive volume pot. Change this cap to 68pF for a huge increase in treble quality in the overdrive stage. The cap needs to be there as with the cap totally removed there is a bit too much treble and the channel switching starts to pop a little. BTW, the volume pot is a dual 1M pot with one stage changing gain in the preamp, and the other as a standard master volume.
2. C72 is a 47pF treble bleed cap on the overdrive gain control (the famous bright cap). Parallel this cap with a 820pF cap to get more Marshally highs at low/mid gain settings.
These two simple mods make a big difference in the overdrive tone. They don't affect much else though. I am very happy with the amp with just these mods. The biggest benefit is you don't need the bright switch for overdrive to sound good with these mods; if you engage this switch it can also make the clean channel too bright.

Насколько я понял в MHZ15, надо заменить C59 (220pF) на 68pF и паралельно C58 (47pF) поставить 820pF? Правильно?
