no you won't because old clients use the original signature verification algorithm but BSV for all transactions (unlike bitcoin) is enforcing a new algorithm that is outlined in BIP-143 known as Transaction Signature Verification for Version 0 Witness Program, that is a part of SegWit soft fork.

ps. that is the absurdity of both bcash and bcashsv. they both bashed SegWit a lot and they both adopted most of it. heck bcash addresses are even bech32 addresses (new format that is used only by SegWit addresses)!!!
