не факт. например старые гибсона eb например дуют очень крепко так, не хуже активов. и darkstarы датчики тоже мощный выхлоп дают...
а вот пиндос-копипаст о т40:
"BUT I gotta tell you, this damn thing is the PERFECT ROCK BASS (well, except for the weigh that is). The best comparison I can make is that it is a cross between a RIC, Jazz & a Pbass! What a freaking monster! This thing played through my 410HLF & B2R Ampeg head tore the hell out of the place! It was AT LEAST 3 times LOUDER than my V63 and about TWICE as loud as my AlemRIc! I had to LOWER the amp volume by 2/3's the setting for my RIC! It is THAT LOUD! Not to mention, the SUSTAIN is to DIE FOR. While it was LOUDER, it isn't as clean or as defined as the RIC basses"
